JavaScript Enums

This tutorial will discuss how to define Enums using curly brackets and upper case letters in JavaScript.

Define Enums in JavaScript

Enums, also known as enumerations, are used to define constant values in JavaScript. You can late use these values in your code. To define the Enums, you can use the const keyword and curly brackets. The name of the Enums will be in upper case letters, and the value will be defined after a colon, and a comma will separate each Enum from the other Enums. For example, let’s define some Enums and get their value by using the name of the Enum and show it on the console. See the code below.

const myEnums = {
  FIRST: 1,
  SECOND: 2,
  THIRD: 3,
}

let a = myEnums.FIRST;
console.log(a)

Output:

1

You can save any data type value inside the Enums like string, integer, etc.
