How to assign multiple variables to different value using 'for loop' in js

Question

I was trying to assign multiple variables that i stored in an array to different variables that i stored in an array using the for loop. Here is what i have tried but didn't get my wanted result. Instead it changed the variable array to the contents in the other array.

let varOne, varTwo, varThree;

let varArray = [varOne, varTwo, varThree]
let valueArray = ['value-one', 'value-two', 
'value-three']

for (let i = 0; i < varArray.length; i++) {
    varArray[i] = valueArray[i]
}

You can’t make an array of variables like that. Maybe reconsider your data structure. — skara9

you are using array which is the same thing just directly assign value in array and access it with index, why you want to use thi short of structure , or else use javascript object, it contains key value. — Nixit Ahir

No practical way, unless you choose to make globals and access them as properties… But you most likely do not need that nor is it a good idea. Consider using an object instead. — skara9

This is impossible. Variables can't be modified like this. You just created a copy.

I not really understand what do you want to solve, but with destructuring an array you can assing values to multiple variables.

let [varOne, varTwo, varThree] = ['value-one', 'value-two', 
'value-three'];

console.log(varOne, varTwo, varThree);

Or you cam map all the arrays into key-value pairs of an object.

let varArray = ["varOne", "varTwo", "varThree"]
let valueArray = ['value-one', 'value-two', 
'value-three']

let res = {};
varArray.forEach((key, i)=> {
  res[key] = valueArray[i];
});

console.log(res);

// or in an array of object with map...
let res2 = varArray.map((key, i)=>{
    return {[key]: valueArray[i]};
  }
);

console.log(res2);

Use objects

let data={
 varOne:"value-one",
 varTwo:"value-two",
 varThree:"value-thress"
}
