String in JavaScript is a sequence of characters. And capitalizing characters of words in a JavaScript string will change each character of the string with the capital letter of it.

To convert words to uppercase we have the following method defined by slicing each character and then converting it to uppercase.

Components are defined as:

Slice():
The slice method will return the specified element of the object and returns it to another object.

For slice(3) for the array [3,5,6,8,9] will give 8.

toUpperCase():
The method will return the uppercase changed the value of the character. For example: for 'f' input, the output is 'F'.

charAt():
returns the charter at the given index.

Program to capitalize each character of the sting using JavaScript

< script >
	function capitalizeEachWord(str) {
		var cstr = '';
		str.split('').forEach(function(char) {
			cstr = cstr + char.toUpperCase();
		});
		return cstr;
	}
	console.log("Hello, world!")
	var x = "learning JavaScript at include help"
	var y = capitalizeEachWord(x);
	console.log('x = ' + x);
