Remove the Last Character from a String in JavaScript

In the world of JavaScript, manipulating strings is a common task for developers. One such operation you might find yourself needing is removing the last character from a string. Fear not, as JavaScript provides several ways to accomplish this task with ease. Let's explore different methods and see how they work!

Different Ways to Remove the Last Character

1. Using slice()
2. Using substring()
3. Using Regular Expressions

1. Using slice()

Sometimes, simplicity is key. The slice() method is a straightforward way to trim the last character from a string.

let originalString = "Hello, World!";
let newString = originalString.slice(0, -1);
console.log(newString); // Outputs: Hello, World

2. Using substring()

The substring() method is another handy option. It's similar to slice() but uses different parameter values.

let originalString = "Hello, Universe!";
let newString = originalString.substring(0, originalString.length - 1);
console.log(newString); // Outputs: Hello, Universe

3. Using Regular Expressions

For those who love the power of regular expressions, here's a regex approach:

let originalString = "Greetings, Galaxy!";
let newString = originalString.replace(/.$/, '');
console.log(newString); // Outputs: Greetings, Galax
