How to Remove the Last Character from a String in JavaScript

In JavaScript, there are several ways to remove the last character from a string by w3school. We'll explore three different methods for achieving this:

Method 1: Using slice method

The slice(0, -1) method takes a portion of the string starting from the beginning (index 0) and excluding the last character (index -1), effectively removing the last character.

// Sample string
let originalString = "Hello, World!";

// Remove the last character using slice

Method 2: Using substring method

// Sample string
let originalString = "Hello, World!";

// Remove the last character using substring

Method 3: Using string manipulation

The slice(0, - 1) method also achieves the same result, taking a substring from the beginning and excluding the last character.

// Sample string
let originalString = "Hello, World!";

// Remove the last character using string manipulation
