How Can Computed Property Names Simplify Object Literal Creation in JavaScript?

Using Computed Property Names in JavaScript Object Literals

In JavaScript, it is possible to utilize computed property names to define properties dynamically within an object literal. This allows for the assignment of a variable's value as the property name, as in the following example:

var myVar = "name";
var myObject = { [myVar]: "value" };

Prior to ES6

Before the introduction of ES6, the square bracket notation had to be employed to achieve this:

var myObject = {};
var myVar = "name";
myObject[myVar] = "value";

However, this approach involved creating the object first and subsequently assigning each property individually, making it less concise.

ES6 and Computed Property Names

With the arrival of ES6, the computed property name syntax emerged:

[myVar]: "value"

This syntax allows for the direct assignment of a variable's value as the property name within an object literal, simplifying the process.
