I'm still stuck on this shit:

  var ammountToCustomer = Number( ( cash - price ).toFixed(2) );

cid.reverse(); // reverse the cid to work from largest denoms down to smallest.

var change = cid.reduce( function ( accumArr , currentArr , index) {
var noteValue = BANKNOTES[currentArr[0]];
var availableInDrawer = currentArr[1] ;
if (false) {
}
return accumArr;
} , []);

if ( Number( ammountToCustomer.toFixed(2) ) > 0) {
return "Insufficient Funds";
}
if ( cid.every(function (val) { return Number( val[1].toFixed(2) ) === 0; }) ) {
return "Closed";
}
// Here is your change, ma'am.
return change;
}

I know that somewhere I need to do a:

accumArr.push( [ currentArr[0] , someValue ] );

And somewhere else I need to do a
ammountToCustomer = Number( ( ammountToCustomer - someValue ).toFixed(2) );

So frustrating.
I can kind of see stuff.
The if (false) was me playing with junk because I didn't know what the hell I was supposed to do.

Waypoint: Iterate Through an Array with a For Loop

// Example
var ourArr = [ 9, 10, 11, 12];
var ourTotal = 0;

for (var i = 0; i < ourArr.length; i++) {
ourTotal += ourArr[i];
}

// Setup
var myArr = [ 2, 3, 4, 5, 6];

// Only change code below this line
var total = 0;
for (var i = 0; i < myArr.length; i++) {
console.log(total += myArr[i]);
}
Hmm that didnt help i have both sys up No fire blowing out of the battery back up. And trying @revisualize

@JLuboff yeah man first one we could just chill all weekend in Flagstaff without having to travel or go to family event
I made the best steak ever too, smoking it with mesquite for like 30 min then searing, so good!
How was yours?

@JLuboff I used my relaxing time to work on my Voting app haha
Just about finished it, now adding some validation stuff for React
Jason Luboff
@JLuboff
Apr 23 2018 15:59
Awesome, I'm sure your voting app is much more robust than mine is :)
Christopher McCormack
@cmccormack
Apr 23 2018 16:00
in the end does about the same thing though haha
and probably with a much larger file size
Jason Luboff
@JLuboff
Apr 23 2018 16:01
True..but for example..I don't have any validation
Christopher McCormack
@cmccormack
Apr 23 2018 16:01
but I really wanted to dig into some different tools and functionality, it was fun
Jason Luboff
@JLuboff
Apr 23 2018 16:01
Mine also isn't really a "full-stack" app since I'm not using React or angular or anything like that
Christopher McCormack
@cmccormack
Apr 23 2018 16:01
I don't think it required that though?
as long as it's frontend + backend?
JS/HTML/CSS/Node basically?
Jason Luboff
@JLuboff
Apr 23 2018 16:02
Correct, not required
Christopher McCormack
@cmccormack
Apr 23 2018 16:02
so yours is full stack :)
I may try out Vue for my next project
Jason Luboff
@JLuboff
Apr 23 2018 16:03
but I think thats their idea of things, is to have you build it using MERN or MEAN just based on the foundation of the FCC Map (frontend -> data viz -> backend)
Christopher McCormack
@cmccormack
Apr 23 2018 16:03
it's tough to tell without them explicitly stating it I guess - they push templating during the backend stuff so I just assumed they expected that
Jason Luboff
@JLuboff
Apr 23 2018 16:05
Ya...maybe the next version will have better descriptors
Christopher McCormack
@cmccormack
Apr 23 2018 16:06
Maybe - really at the point of building webapps your requirement to stick with FCC is pretty minimal
you can basically start building whatever you want
Jason Luboff

fuck man wrong picture
im having an issue with bcrypt and no idea why
if someone can give it a look
import bcrypt from "bcrypt";

export default (password) => {
const salt = bcrypt.genSaltSync(10);
return bcrypt.hashSync(password, salt);
}
I console log the argument passed and its there
I also did the same for salt and its everything there
but when I run it the error above shows up
router.post("/register", [
body("email")
.isEmail()
.withMessage("Invalid email!"),
body("password")
.isLength({ min: 4 })
.withMessage("The password minimum length is four characters!"),
body("name")
.isLength({ min: 1 })
.withMessage("You need to write your name!")
], (req, res) => {
const errors = validationResult(req);
if (!errors.isEmpty()) return res.error(409, errors.array()[0].msg);

const { email, name } = req.body;
const password = encryptIt(req.body.password);

try {
connection.query("SELECT * FROM users WHERE email=?", [email], (err, user, fields) => {
if (err) throw new Error(err);
if (user) return res.error(409, "The email it's already in use by another user!");

connection.query("INSERT INTO users SET ?", { email, name, password }, (err, user, fields) => {
if (err) throw new Error(err);
console.log(user);
res.send(user.affectedRows);
});

});
} catch (e) {
res.error(500, "Something went wrong please refresh the page and try again", e);
}
});
this is the route in cause its needed
the function its called encryptIt
Christopher McCormack
@cmccormack
Apr 23 2018 20:18
show your function
Tiago Correia
@tiagocorreiaalmeida
Apr 23 2018 20:19
its above
I use bcrypt
generate a salt
and then hash it
done this thousand of times
but today this aint being friendly :D
Jason Luboff
@JLuboff
Apr 23 2018 20:21
Did you try adding some pepper? I find it really enhances the flavor
Tiago Correia
@tiagocorreiaalmeida
Apr 23 2018 20:22
I guess it could make it more tasty
Christopher McCormack
@cmccormack
Apr 23 2018 20:22
did you test your function outside of your program?
just pass in text and number value?
Tiago Correia
@tiagocorreiaalmeida
Apr 23 2018 20:24
const test = encryptIt("teste");
same thinbg
same error
Christopher McCormack
@cmccormack
Apr 23 2018 20:26
How are you using import? with experimental flag?
Tiago Correia
@tiagocorreiaalmeida
Apr 23 2018 20:26
wait a second
Christopher McCormack
@cmccormack
Apr 23 2018 20:26
no
Tiago Correia
@tiagocorreiaalmeida
Apr 23 2018 20:27
two then :D
import bcrypt from "bcrypt";

export default (password) => {
const salt = bcrypt.genSaltSync(10);
const encriptedPassword = bcrypt.hashSync(password, salt);
return encriptedPassword;
}
if I assing it to a variable works
strange I made it work really a few times just by returning the function itself with the arguments but well I dont know thanks tough you made me split this even more
Christopher McCormack
@cmccormack
Apr 23 2018 20:28
hmm require wraps your code, maybe by importing you're changing it, try requiring bcrypt instead maybe?
I'm still a little confused by how require works though even after reading several articles :)
Tiago Correia
@tiagocorreiaalmeida
Apr 23 2018 20:29
fu** me..
bcrypt expects a salt and a string
it literally says it on the error and im sending a number on the post request.. :D
Christopher McCormack
@cmccormack
Apr 23 2018 20:30
why is password a number?
Tiago Correia
@tiagocorreiaalmeida
Apr 23 2018 20:31
cause im using postman to make the request on the api and I forgot to wrap it around on double quotes :\
Christopher McCormack

first the brocoli now this
Christopher McCormack
@cmccormack
Apr 23 2018 20:31
so why did changing your function work? did you also change your test?
Tiago Correia
@tiagocorreiaalmeida
Apr 23 2018 20:31
I just got the function back to what it was the issue was really pass a number to the bcrypt function

Evening guys
Can anyone give me a hint as to why my code doesn't work?

function getIndexToIns(arr, num) {
arr.sort(function(a, b) {
return a - b;
});
for (var i = 0; i < arr.length; i++){
if (num > i && num <= i+1) {
arr.splice(i+1,0,num);
}
}
return arr;
}

getIndexToIns([40, 60, 70, 80, 20, 10], 50);

Apr 23 2018 21:15
@Kohota107 What challenge is that? The name of the function tells me that a number (index) should be the result of the function call. But you return an array.
Tom
@moT01
Apr 23 2018 21:15
that if test doesnt look right
Josh Queen
@josh-queen
Apr 23 2018 21:15
It's the where do I belong challenge
But I haven't got to the index position yet
I just want to print the array with the integer in the right place
Then I'll worry about returning the index (which will be a lot easier!)
@moT01 can you give me a clue as to why?
Tom
@moT01
Apr 23 2018 21:16
if (num > i && num <= i+1) { ? so the same as if num === i+1
alpox
@alpox
Apr 23 2018 21:16
@Kohota107 num > i` you compare the number with an index - your indices are 0-5, but the numbers are 10-80. You should be comparing the number with array elements, not indices
Josh Queen

electron actually sounds fun let me us know if you do
Jason Luboff
@JLuboff
Apr 23 2018 23:12
:+1:
Probably be a little quicker to do it with C# (winforms are so stupid easy to make..you jsut drag and drop, but limited customization)
I really like the idea of Electron though. Essentially turn a web app into a standalone app. Kind of nice but still carries some of the same issues or limitations
Christopher McCormack
@cmccormack

seems like a useful tool. I use more electron apps than not lately it seems, I'm on slack/vs code all the time

looks at how much ram atom takes up, with no files open (500mb)
Christopher McCormack
@cmccormack
Apr 23 2018 23:28
Atom is a hog I never really liked it, laggy and crashed a lot when I first used it
VS Code blows atom away, sorry @JLuboff :)
Jason Luboff
@JLuboff
Apr 23 2018 23:28
Err... then there's something wrong with your Atom lol. I have two files open and it's only using 40 MB...

I have about 20 tabs open too and Chrome only using 650MB, not too shabby
Jason Luboff

,....12 tabs with FF... only 222 MB
What are you guys doing to your machines :joy:
Christopher McCormack
@cmccormack
Apr 23 2018 23:30
most of that really depends on your extensions
people don't realize something like an Ad Blocker uses a really big file(s) stored in memory for fast access, and complain their Chrome is slow compared to other browsers not running any extensions
Jason Luboff
@JLuboff
Apr 23 2018 23:31

Is gitter built in electron? It's only using 12 mb
Brad
@bradtaniguchi
Apr 23 2018 23:32
AFAIK yea its an electron app
the VScode guys must do heavy optimzations tho cuse its ram usage is really low compared to other electron apps.

VS Community is pretty good as an IDE..I just still prefer atom over it for text editor. I run Atom on a vertical screen and it gives me the most working space
