string created using a sequence of characters, "Yes, You Can DO It!". In JavaScript, we can create a string in a couple of ways: One interesting fact about strings in JavaScript is that we can access the characters in a string using its index. The index of the first character is 0, and it increments by 1. So, we can access each of the characters of a string
like this: The image below represents the same thing: Apart from its
ability to access string characters by their indices, JavaScript also provides plenty of utility methods to access characters, take out a part of a string, and manipulate it. In this article will learn about a handy string method called The After splitting the string into multiple substrings, the Let's understand how this works with an example. Here is a string created using string literals:

The main purpose of the How to Split a String by Each CharacterYou can split a string by each character using an empty string('') as the splitter. In the example below, we split the same message using an empty string. The result of the split will be an array containing all the characters in the message string.

How to Split a String Using a Non-matching CharacterUsually, we use a splitter that is part of the string we are trying to split. There could be

Let's split this string at the period (.), exclamation point (!), and the question mark
(?). We can write a regex that identifies when these characters occur. Then we pass the regex to the
