@Chrono79 so it is `(matrix[r+v.r]||[])[c+v.c]` OR `0`?
Nov 08 2017 01:11
Could it be used to convert a string value to a numeric value?
You might want to look at the operator precedence table?
And here is an interesting article about bitwise operators - just something to ponder, it might not be directly relevant to this usage / example.

An interesting possible usage from this MDN link

In the section on Bitwise Logical operators:

The operands are converted to 32-bit integers and expressed by a series of bits (zeroes and ones). Numbers with more than 32 bits get their most significant bits discarded. For example, the following integer with more than 32 bits will be converted to a 32 bit integer:

So doing a bitwise or of a numeric value represented as greater than 32 bits with `0` will truncate the most significant bits, and pass the lower bits unchanged...

I am using fs but I like to check my data every step of the way
getting this error
``````fs.js:641
return binding.open(pathModule._makeLong(path), stringToFlags(flags), mode);``````
Dont worry i got the buffer :)
I wasn't passing the correct path. I checked the path and found my own error. I think I need a debugging stick to beat my own self when I find a simple mistake.

Hey guys, is it possible to do something like this?

func(`\${cat}`, sleep(cat));
func(`\${dog}`, sleep(dog));

const sleep = (defaultArgument1, defaultArgument2, animal) => {
// defaultArgument1 and defaultArgument2 will be used later
console.log(`The \${animal} is asleep`)
}``````

@lyzamatrix Personally, I'd have to say that the fastest, and most fun, way to learn JavaScript is to build things with it (whether that be algorithms, websites or apis). Also I'm not talking about those websites that have you learn by following instructions forever, I'm talking about doing your own projects that challenge your knowledge of the language and if you don't know how to do something then you can learn right there. As for algorithm challenges, the best ones would probably be http://codewars.com and http://hackerrank.com

@Tejparn To format code here on chat put it between lines of backticks:
```js
```
gives

``var answer = 42;``

But really, don't dump such large code blocks on chat, but use some hosting service like github gists or pastebin, or a codepen or jsbin or whatever where appropriate.

About the problem - I have never used canvas. You do call `drawScore` and have ensured it's running (for example by logging something from the function), right?

You call or invoke a function by writing its name and placing a pair of parentheses after, in this case without passing any arguments.

Garrus Napp
@GarrusNapp
Nov 08 2017 13:49
@rohyadav first, adding element doesn't work as you want, you create <li></li> and text node with `item X` after that
Nov 08 2017 13:49
li
Garrus Napp
@GarrusNapp
Nov 08 2017 13:49
instead of `<li>itemX</li>`
@rohyadav that is why when you click your created list you get `List item was clicked!`
without nr
Stephen James
@sjames1958gm
Nov 08 2017 13:51
1. you are appending the text node to the ul not the li
2. you are not adding an id to your new li so your console.log has no id to output
``````  li.id = "post-" + listLength;

li.appendChild(nextNode);``````
Nov 08 2017 13:52
when i click on list 7 that newly created
and if i click 6 that already in the dom that worked
Stephen James
@sjames1958gm
Nov 08 2017 13:53
@rohyadav `console.log("List item ", e.target.id.replace("post-", ""), " was clicked!");`
your console.log is using the id of the list item, but your new list item has no id
@rohyadav You don't even need to create the text node
``````  li.id = "post-" + listLength;
li.textContent = "Item " + listLength;``````
Nov 08 2017 13:55
yes if even no id for now .. atleast when i click in any newly created list item that time loggin in console
ok
can you fork and update and share with me jsfiddle

For example, functions and variables share the same namespace, so should not have the same name. Not sure how jsfiddle integrates its JavaScript tab, though.

@alexandrupintilei many of your variable names are incorrect. Also plus isn't defined before use. Try adding this at top of your html:
``````<script>

function plus(){
var minus = document.getElementById('check2');
var inmultire = document.getElementById('check3');
var Impartire = document.getElementById('check4');
var newValue = 0;
var textP = document.getElementById('text');
var plus = document.getElementById('check1');
var n1 = parseFloat(document.getElementById('num1').value);
var n2 = parseFloat(document.getElementById('num2').value);
newValue = n1+n2;
textP.innerHTML="x=" + newValue;
}

</script>``````

jsfiddle packs this stuff into its own scope, using window.onload. So instead of

``<input type="checkbox" name="check" id="check1" onClick="plus()">Adunare<br>``

and

``````debugger;
var plus = document.getElementById('check1');
var minus = document.getElementById('check2');
var inmultire = document.getElementById('check3');
var Impartire = document.getElementById('check4');
var newValue = 0;
var textP = document.getElementById('text');

function plus(){
var n1 = parseFloat(document.getElementById('num1').value);
var n1 = parseFloat(document.getElementById('num2').value);
newValue = n1+n2;
textP.innerHTML="x=" + newVal;
};``````

try

``<input type="checkbox" name="check" id="check1">Adunare<br>``

and

``````var plusCheck = document.getElementById('check1');
var minusCheck = document.getElementById('check2');
var inmultireCheck = document.getElementById('check3');
var ImpartireCheck = document.getElementById('check4');
var newValue = 0;
var textP = document.getElementById('text');

plusCheck.addEventListener("click", plus); // this is equivalent to the onclick, but in a scope that knows plus function

function plus(){
var n1 = parseFloat(document.getElementById('num1').value);
var n2 = parseFloat(document.getElementById('num2').value);
var newValue = n1+n2;
textP.innerHTML="x=" + newValue;
};``````

@JLuboff yoooo remember i was tryin to do react w passport?
that was a mistake
wasnt able to do it, got passport working with a basic MEN stack app
but Okta is best for auth with react

Christopher McCormack
@cmccormack
Nov 08 2017 17:38
@breese8009 this is a frontend solution only - if you want to use react with passport you would need to setup some backend routing for login, then you could use passport
@tiagocorreiaalmeida looks really nice - there is some slight buggyness where it tries to fill the area between two points on the graph.
Christopher McCormack
@cmccormack
Nov 08 2017 17:43
@tiagocorreiaalmeida after removing some stocks the graph bugged out completely and wouldn't show any stock
@tiagocorreiaalmeida and I'd still recommend putting the stock symbol input above the graph so if you're on a smaller screen you don't miss it.

@JLuboff Fine. I did a clean 6 minutes breath hold some time ago. With something like that I should have a chance for a medal in spring national championships. Haven't really had a chance to train length diving this fall but now possible again. Possible that I also do that in the nationals if I improve somewhat.

@NehemiahK i find algorithms a good way to expand the mind, and learn the logic of how to take things apart and sort and rearrange them.. in some ways that's the basis of dealing with data
me and some others who are done most/all of the fCC ones have moved over to other sites like codewars and hackerrank that are mostly just algo type challenges.. for fun and the opportunity to keep the skills fresh
