In this article, we would like to show you how to create a variable using a user-defined name in JavaScript.

Quick solution:

// ONLINE-RUNNER:browser;

let variableName = 'exampleName';
let value = 5;

this[variableName] = value;

console.log(this[variableName]);

Practical example

In this example, we create a variable using a user-defined name with the help of an object.

// ONLINE-RUNNER:browser;

let variableName = 'exampleName';
let value = 5;

let object = {
    [variableName]: value,
};

console.log(object[variableName]);
