If you need to remove the last character from a string in javascript, there are many ways you can use these for that. In this tutorial, we will show you 3 approaches to removing the last character from a string in JavaScript by w3school.
How to Remove the Last Character from a String in JavaScript
Here are 3 approaches to removing the last character from a string in JavaScript by w3school:
- Approach 1: Using
substring()Method - Approach 2: Using String Slicing Method
- Approach 3: Using ES6 Arrow Functions and
slice()
Approach 1: Using substring() Method
The substring() method is similar to slice() but has slightly different syntax. It also allows us to remove the last character by specifying the desired substring range.
To remove the last character from string in javascript, you can use substring(0, str.length - 1):
const mystr = "Hello, world!";
const RemoveLastCharString = mystr.substring(0, mystr.length - 1);
console.log(RemoveLastCharString); // "Hello, world"
Approach 2: Using String Slicing Method
The slice() method is a classic approach to remove last character from a string by specifying the specified range.
For example, if you want to remove the last character from a string, you can use slice(0, -1):
// Original string
let myString = "Hello, World!";
// Remove the last character
let stringRemoveLastChar = myString.slice(0, -1);
console.log(stringRemoveLastChar); // Output: Hello, World
Approach 3: Using ES6 Arrow Functions and slice()
A modern approach involves using the spread operator (...) to convert the string into an array, removing the last element, and then joining it back into a string.
Here is an example of removing the last character from a string using es6 arrow function with a slice():
// Original string
let originalString = "Hello, World!";
// Remove the last character
let stringWithoutLastChar = [...originalString].slice(0, -1).join('');
console.log(stringWithoutLastChar); // Output: Hello, World

In this tutorial, you have learned 3 approaches to removing the last character from a string in JavaScript. Choose the approach that fits your preference and coding style.
