How to trigger the event of active using jquery, for a give period? It's like I'm holding the click for a moment.
Claudio Restifo
@Marmiz
Nov 03 2017 03:04
@Morched23MJ you can detect mousedown and mouseleave if you want to see a user "holding" a click :)
Morchid Chellali
@Morched23MJ
Nov 03 2017 03:07
I'm asking that, because on the Simon Game you have to click some buttons, so the user can remember them. So I'm asking how to trigger the click event, for a longer period, in order to let the user actually notice it, and slow down the process.

@Morched23MJ the "easiest" animation goes from changing the opacity, to using box-shadow properties.
More complex require some timing transitions

Nov 03 2017 08:34
it was 4 hours total doing tests back to back
Henry

Nov 03 2017 08:35
what were the positions, and what where the tests like?
Long Nguyen
@longnt80
Nov 03 2017 08:35
and the first company was ready to give me the offer
for the first company, it was all algorithm tests

front end developer position?
all js tests
Long Nguyen

for the second, it was a pair-programming session where I had to solve one algorithm and build a react component
yep front end, and all js

Nov 03 2017 08:37
did you solve all the algorithms
Long Nguyen

what challenges? do you remember? @longnt80
Long Nguyen
@longnt80
Nov 03 2017 08:39
yes I have it back with me, need to translate it to English though
it's not too hard but harder than algorithms that I did in some previous interviews
Marianissimus
@Marianissimus
Nov 03 2017 08:40
you would help us so much...
anyway, harder than the fcc challanges?
Long Nguyen
@longnt80
Nov 03 2017 08:40
not harder, I just didn't have enough time
30 mins for 4 algorithms
Marianissimus
@Marianissimus
Nov 03 2017 08:40
quite a short time

Nov 03 2017 08:50
@Marianissimus @GitHub-Henry
Here's the first one:
Write a function to print out numbers from 1 to 100, with these conditions:
• First number that can divide by 3 will be printed out as letter D. Second number can divided by 3 will be printed as DD. And the nth number can be divided by 3 will be printed out as n letters of D.
• First number that can divide by 5 will be printed out as letter S. Second number can divided by 3 will be printed as SS. And the nth number can be divided by 3 will be printed out as n letters of S.
• First number that can divide by 3 and 5 will be printed out as letter DS. Second number can divided by 3 and 5 will be printed as DSDA. And the nth number can be divided by 3 will be printed out as n pairs of DS.

is this one you finished
how long did it take

@Marianissimus
Nov 03 2017 08:52
Oh, it's a variation of the fizzbuzz challange, but a bit harder
Long Nguyen
@longnt80
Nov 03 2017 08:52
Here's the result example: 1,2,D,4,5,DD,...
yeah I finished this one
Marianissimus
@Marianissimus
Nov 03 2017 08:52
nice
Henry
@GitHub-Henry
Nov 03 2017 08:52
good job
Long Nguyen
@longnt80
Nov 03 2017 08:52
I think I took close to 20mins to finished 2 of them
Henry
@GitHub-Henry
Nov 03 2017 08:53
do you remember the other one
Long Nguyen
@longnt80
Nov 03 2017 08:53
I was doing the third one and it was out of time
yep I have the algorithm on paper with me
let me give you the other one which I finished
Write a function which takes in an array of continuous number and a number in that array. The rotate the array by that number. Example:
array: [1,2,3,4,5,6,7]
number: 3
result: [4,5,6,7,1,2,3]
this one is easier
Henry
@GitHub-Henry
Nov 03 2017 08:57
looks like you did well
so where do things stand with the companies, do you prefer one over the other
Long Nguyen
@longnt80
Nov 03 2017 09:01
@Marianissimus @GitHub-Henry
Write a function to print out an array of number. The next number will describe the previous number. Array starting with number 1.
Example:
First number is 1
Second number: 1 number of 1
Third number: 2 numbers of 1
Here's the result array: [1, 11, 21, 1211, 111221, 312211,...]
Marianissimus
@Marianissimus
Nov 03 2017 09:01
@longnt80 ok, so it gives you the argument 3, you must give the result of 3+1 and the continuous array?
Can't wait to try them all
Long Nguyen
@longnt80
Nov 03 2017 09:02

so it gives you the argument 3

what do you mean?

I had a hard time understand what the algorithm wanted
could be the writting
Henry
@GitHub-Henry
Nov 03 2017 09:04
sounds like you were up to the mental gymnastic challenges, :+1:
so what's next
Marianissimus
@Marianissimus
Nov 03 2017 09:04
the initial arr is of numbers 1-7, right? ok, whatever number they give you, it should be used to splice the... I have some ideas. I'll try them all and then post my results here
Long Nguyen
@longnt80
Nov 03 2017 09:05
@Marianissimus yes, I thought you were talking about the other algorithm
Tiago Correia
@tiagocorreiaalmeida
Nov 03 2017 09:05
what was the "type" of job? just curiosity
Henry
@GitHub-Henry
Nov 03 2017 09:05
@Marianissimus ok, but you need to do it in a timed manner, @longnt80 how much time did you have for these
Long Nguyen
@longnt80
Nov 03 2017 09:05

so what's next

one company already gave me the job
I'm waiting for the other company's response

Henry
@GitHub-Henry
Nov 03 2017 09:06
@Marianissimus to simulate the condisions
Long Nguyen
@longnt80
Nov 03 2017 09:06

how much time did you have for these

30mins total for 4

Marianissimus
@Marianissimus
Nov 03 2017 09:06
the second one seems to want you to convert a number to a string of a specific length... mhm...
Long Nguyen
@longnt80
Nov 03 2017 09:06
I'm translating the last one
Henry
@GitHub-Henry
Nov 03 2017 09:07
@Marianissimus ok you should only give yourself 30 minutes from start to finish, and your thinking about is should reduce your time to solve, so less than 30 minutes
Long Nguyen
@longnt80
Nov 03 2017 09:09
Last one:
Write a function that take in an array. Return the number of instance of each number:
Example: [1,3,1,2,4,1,4,5,2,3,2]
1: 3 instances
3: 2 instances
2: 3 instances
4: 2 instances
5: 1 instances
Marianissimus
@Marianissimus
Nov 03 2017 09:09
Yes, I got that. I'll try to do them in 30 min
what's curious is that they all are about arrays / array methods, not a single one about objects
Did they allow you to search for methods on the net? on mdn or something?
Henry
@GitHub-Henry
Nov 03 2017 09:11
@longnt80 you totally would have had this one, given enough time
Long Nguyen
@longnt80
Nov 03 2017 09:11
yeah, I think they only care about how you solve algorithms which often has to do with array?
yeah, I can search anything
I think given the timeframe, googling won't help much
Marianissimus
@Marianissimus
Nov 03 2017 09:12
oh, that's great. I won't feel like cheating.
Henry
@GitHub-Henry
Nov 03 2017 09:12
@longnt80 did they want other skills besides JS
Long Nguyen
@longnt80
Nov 03 2017 09:12
and it was in Vietnamese, I could run out of time trying to translate them to find answer on Google
Marianissimus
@Marianissimus
Nov 03 2017 09:12
yes, but this is just to find the syntax of the method, the last one seems to use indexOf, but im not sure...
Ok, guys, see you in 30 mins:)

but they also emphasize that they want people that can use vanilla JS
both of them
@tiagocorreiaalmeida they both do web apps

@tiagocorreiaalmeida they also mentioned canvas, html5 games

@alpox yeah, I have some experiments with canvas so it has algorithm and math in there
alpox
@alpox
Nov 03 2017 09:21
@longnt80 I kinda like that math though
Long Nguyen

@thomasfaller
Nov 03 2017 09:41

Hey guys,
I’m working on a script that has a soccer table with numbers of wins, draws and losses and I’d like to build an array of object to store that such as:
let l1Table = [{name: "Paris", W: 9, D: 2, L: 0, Pts: 29}, {…..}, etc]

pretty simple but I’d like the “Pts” value to be calculated and returned dinamically as I update the W,D or L values (makes sense?)

So I thought about storing a function inside Pts such as
let tableTest = [ { W: 3, L: 4, Pts: function() { return ……. blablabla } } ];

What would be the most efficient way to do that?
If I create an outer function and call it from inside each object (here each club would be its own object), will it be able to access the proper W value through this.W for example?

Any thoughts?

Pieter Stokkink
@forkerino
Nov 03 2017 10:20
You don't need a function on each object, it would make more sense to put it on the prototype of the objects. @thomasfaller

Stephen James
@sjames1958gm
Nov 03 2017 10:33
@thomasfaller Your function could also receive the object as a parameter and update the points. Or since it can be calculated, you don't need to store it at all.
Creating a constructor function for the objects and assigning the function to the prototype seems the js "OO" way to go.

Tiago Correia @tiagocorreiaalmeida Nov 03 2017 15:35 @Yofri if that's mongodb that looks quite strange tbh what are you using to connect to the mongo tough? Johnny @JohnnyBizzel Nov 03 2017 15:35 @Yofri It's the way you phrased the question. Like a quizmaster. Tiago Correia @tiagocorreiaalmeida Nov 03 2017 15:35 mongoose or mongodb native? Johnny @JohnnyBizzel Nov 03 2017 15:35 @lawrencelee93 No idea. Just looks odd compared to how I did it. Like how will anyone get to that route. Tiago Correia @tiagocorreiaalmeida Nov 03 2017 15:36 or sql? yofri @yofriadi Nov 03 2017 15:36 @tiagocorreiaalmeida no, its postgre Tiago Correia @tiagocorreiaalmeida Nov 03 2017 15:36 oh ok, time to stepback ;) gl mnate yofri @yofriadi Nov 03 2017 15:36 haha ok Johnny @JohnnyBizzel Nov 03 2017 15:37 @Yofri Never seen await so no idea. If it is async, should res.redirect be in a callback? yofri @yofriadi Nov 03 2017 15:38 @JohnnyBizzel yes it is on try scope, so it is a kind of callback Johnny @JohnnyBizzel Nov 03 2017 15:38 @lawrencelee93 if it's a node app you should test it on glitch.com not codepen @Yofri You would have to explain the code to me better. I will pass.

Is the purpose of this to be able to use React with 3rd party libs that are established game engines? Or is the purpose to learn to use react components to control the events of the game? I feel very dense about how to approach this challenge. Kaz Baig @kbaig Nov 03 2017 19:01 @greaneym Latter But nobody is stopping you from doing the former Margaret Greaney @greaneym Nov 03 2017 19:03 So use react components to take the place of the arrow control keys?

Kaz Baig @kbaig Nov 03 2017 19:06 you're not supposed to look at the code What's the point of an example project if you can't play around with it Margaret Greaney @greaneym Nov 03 2017 19:08 @kbaig , I will play the game and see if that helps.

I wrote a function, that is supposed to light up divs, every second, a random button (here, considered divs). It doesn't matter when to click them, I'm just starting, so the problem is, that they light up all at once, and they go back to normal, and then they don't anymore. They're supposed to do that 20 times. Here is the pen: https://codepen.io/Morched23MJ/pen/zEYxGo I appreciate your help. Ask me if you have difficulties with understanding what I'm trying to do. Christopher McCormack @cmccormack Nov 03 2017 19:13 @greaneym if it helps, I did something like this for mine: const ARROW_KEYS = { 'ArrowUp': new Pos(0,-1), 'ArrowRight': new Pos(1,0), 'ArrowDown': new Pos(0,1), 'ArrowLeft': new Pos(-1,0) } ... class App extends React.Component { ... initializeHandlers(){ window.addEventListener('keydown', (e)=> { e.preventDefault() this.characterMove(ARROW_KEYS[e.code]) }) Array.from(document.getElementsByClassName('key')).forEach((item)=>{ item.addEventListener('click', ()=>{ this.characterMove(ARROW_KEYS[item.id]) }) }) } Kaz Baig @kbaig Nov 03 2017 19:13 @Morched23MJ Are you increasing the timeout for each blip or no Muhammad Hasham @MohammadHasham Nov 03 2017 19:14 how can i change color of the text entered in an input bar if it matches with the word in paragraph text? what would be the approach can anyone help? Christopher McCormack @cmccormack Nov 03 2017 19:14 @greaneym React decides how your DOM elements are attached, but you still have to handle your inputs using JS Morchid Chellali @Morched23MJ Nov 03 2017 19:16 @kbaig, nope. One second for all of them. Christopher McCormack @cmccormack Nov 03 2017 19:16 @MohammadHasham you would add an event listener to the input field and every time a change is made, check if the text matches. If it does, you can modify the CSS of the input to make the color green when matching. Muhammad Hasham @MohammadHasham Nov 03 2017 19:17 i have tried that but the problem is how can i make sure that i change only the particular word css change in the paragraph not the whole paragraph Morchid Chellali @Morched23MJ Nov 03 2017 19:17 @MohammadHasham, you could try to set an event listening: $('input').on('focus', functionHere()); ?
Nov 03 2017 19:17

the text is somewhat like this:

<p> Here goes some text </p>

@Morched23MJ @cmccormack
so how can i select a particular word and change it
Morchid Chellali
@Morched23MJ
Nov 03 2017 19:18
Using regular expressions? Depends what you want to do. Can you be more explicit?
Nov 03 2017 19:20
i want to select a work from a paragraph then change its bgcolor that's it
but how do i select a specific word from a paragraph change its color and then fir it in
Christopher McCormack
@cmccormack
Nov 03 2017 19:21
@MohammadHasham you're getting the word from an input box?
Nov 03 2017 19:21
yes exactly.
Christopher McCormack
@cmccormack
Nov 03 2017 19:22
@MohammadHasham so every time there is a change ('input') in the input field, you can parse the paragraph text to see if it exists. You can use regex, or you can split the string into an array and check each value against your input string
Morchid Chellali
@Morched23MJ
Nov 03 2017 19:23
@kbaig, you found any error? :l
Nov 03 2017 19:23
but after splitting it i can't change the property i have tried that

for example

arr[0].style.color = "red"; does not work

Christopher McCormack
@cmccormack
Nov 03 2017 19:23
@MohammadHasham then you would need to add span tags around that word in the p, and add a style changing the color.
Nov 03 2017 19:24
and then i should replace it?
Christopher McCormack
@cmccormack
Nov 03 2017 19:24
or check if there is a span and just modify the color
probably several ways to do it
Morchid Chellali
@Morched23MJ
Nov 03 2017 19:24
What you mean? You could use join(' ') after the splitting and comparing your words?
Nov 03 2017 19:25

@cmccormack

is this somewhat right?

function highlight(high){
res.forEach((value)=>{
if(value == high){
var para = document.createElement('p');
var html = document.createTextNode(value);
para.append(html);
para.style.color= "blue";
text.innerHTML.replace(high,para);
console.log(high);

}
});

Hey guys
Is there a dryer way to write this code. It is 4 different spans that will be clicked.
breakSub.addEventListener("click", function(){
breakTime -= 1;
breakLength.textContent = breakTime;
})

})
