How to assign value to a value string in javascript

Question

I want to assign value to a value string. Sample as below written in javascript

var q="e"; [q]='hio';

e should have value of 'hio'

JavaScript: Assign a value to a string

the above link solves the problem. But using eval is not right approach. So I am looking for better approach.

You could use an object:

var myObj = {};
var q = "e";
myObj[q] = "hio";

console.log(myObj.e);

I got this. Rather than creating an object do we have any other clean way?

Not as written, in your example. Do you have additional context?

[q]='hio' - has a specific meaning already in Javascript. It means, assume the right hand side is an array, take the first element, and store it in q.

I want to take two values. One heading like "Website" and assign second value to it like "www.google.com" .

That’s commonly called a “key/value pair”, where the key is website and the value is google. Search for “store key value pair in javascript” if you’d like to get some other ideas.
