@taburetkin I know how to use it, all I'm asking is if var is only used the first time for reassigning values.
dimtabu
@taburetkin
actually, links i give you completely answers your question, but to get the answer you have to read

@EuphoricPenguin
It looked like just scope.

@taburetkin Saw an article here, so you don't use var to reassign. I never did, but for some reason I was worried lol.

Oh, just saw this and was curious: What is the "?" operator? Is it shorthand, I've only seen it used a couple of times.
Tried to find it on MDN and Google, no luck.
Nvm, found it.
Assigns an optional value based on condition.

@taburetkin
i belive you can sort in one go, like in my example
without creating three additional arrays.

@taburetkin could you please explain what does each step do?

Hi there

I have a 10x4 grid of checkboxes (call it x, y) - I would like to get the coordinates (x, y values) of the checkbox when a user selects one. What data structure can I use to pluck out those coordinates?

I've tried using a Map like so:

 onCheck(e) {
    const productMap = new Map();

    productMap.set('productId', e.path[2].id.split('-').pop());
    productMap.set('productLevelId', e.path[2].id.split('-').pop());
}

The checkboxes are generated dynamically, so I use a click event listener and pass in the checkbox element..

The backend expects from me, a response like this:

{
productId: 4,
productLevelId: 1
}

Any ideas how I can accomplish this?

@taburetkin
when you click on a checkbox then change event is emited
event.target in that case will point to your checkbox dom element
you can add additional attributes to the dom element
<input type="checkbox" data-id="yourProductId" data-levelid="yourLevelId">
and then extract this values in the change event from the event target

@taburetkin thanks - much appreciated, lemme give it a go.

@shekharramola
if I do like this, would you expect array to get modified?
```
   this.myForm.value.arr.forEach(form => {
      this.filesToSend.forEach(element => {
        element = element + '=' + form.password;
        console.log(element);
      });
    });
    console.log(this.myForm);
    console.log(this.filesToSend);
  }
```
inside it is getting modified but no effect on filestosend array

@sjames1958gm
If element is a reference to the value in the array, you are changing the vale of the reference not the value being referred to. So no it would not change the array
Remove that first ‘if’ in the above sentence
Shekhar Ramola
@shekharramola
if statement is not there. where it is?

@yousefMZ
what is the code in codewars ?? javascriptfunction multiply(a, b){
a * b
}
Stephen James
@sjames1958gm
@shekharramola oh lol, I meant the ‘if’ in my response not in your post.

import store from './store/store';

console.log('Before:', store.getState());
sometimes in Node or React we use store.getState() and sometimes store.getState. Without direct invoking, why is that? what is the difference? Thanks

Hi All I have run into a problem I am uanble to call values of Array from different JS file. See the attached code for your refernence

File1//
import {DataVal} from './DateValue';

DataVal.map((item) =>{
console.log ("Date: "+ item.date);
});

File2//

export const DataVal =
[
{
date:"07/08/2010" .........................................
......................................
