如何在js中使用'for循环'将多个变量分配给不同的值

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]
}

Answer 1

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

Answer 2

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);

Answer 3

• Use objects

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