Can we create arrays with for loop, without square bracket in javascript

Question

Im new at javascript. Please help me.

Can we create arrays with for loop, without square bracket. Like :

var ar0 = num0
var ar1 = num1
.
.
var ar"i" = num"i"

i cant define like that :

for (i=0;i<5;i++){

var (ar+i) = num+i

}

i know this isnt array but i want create a lot like this. i have to use "for loop"

Answer 1

You can use something like this:

 let result={};
    for (let i=0;i<5;i++){
        result["ar"+i]= `num${i}`;
    }
    console.log(result);

The result will be something like this:

{ ar0: 'num0', ar1: 'num1', ar2: 'num2', ar3: 'num3', ar4: 'num4' }

I hope that's what you are looking for.

Answer 2

I only see that as a solution :

let ar = Array.from({length:5},(_,i)=>`num${i}`)

Answer 3

Use eval built-in function :

for (i=0;i<5;i++){
    eval("var " "ar"+i + "= num+"i)
}
