How to Capitalize Strings in JavaScript

In this article, you will learn How to Capitalize Strings in JavaScript.

Let’s say you have a string variable named ‘a’ with the value “codesource”.

var a = "codesource";

In order to capitalise the value of a, you can use the toUpperCase() method.

var a = "codesource";

var b = a.toUpperCase();

Note: The toUpperCase() method functions by converting all alphabetical characters in a string to uppercase letters.
