4 Approach Remove the First Character from a String in JavaScript

In JavaScript, manipulating strings is a basic need. If you need to remove the first character from a string, there are several approaches you can take. In this tutorial, we will show you 4 approaches to remove the first character from string in JavaScript by w3school.

How to Remove the First Character from a String in JavaScript

Here are 4 approaches to removing the first character from a string in JavaScript by w3school:

• Approach 1: Using String substr() Method
• Approach 2: Using substring() Method
• Approach 3: Using String Slicing Method
• Approach 4: Using ES6 Arrow Functions and slice()

Approach 1: Using String substr() Method

The substr() method extracts a specified number of characters from a string, starting at a specified index.

For example, if you want to remove the first character from a string, you can use substr(1):

// Given string
let givenString = "Hello, World!";

// Remove the first character
let stringWithoutFirstChar = givenString.substr(1);

console.log(stringWithoutFirstChar);

Approach 2: Using substring() Method

The substring() method helps us to remove characters from a string by specifying the starting index and end index.

To remove the first character, you can use substring(1) to get the substring starting from the second character to the end.

// Given string
let givenString = "Hello, World!";

// Remove the first character
let stringWithoutFirstChar = givenString.substring(1);

console.log(stringWithoutFirstChar);

Approach 3: Using String Slicing Method

The slice() method is similar but can accept only 1 argument. It removes characters from a string by specifying the starting index only.

For example, if you want to remove the first character from a string, you can use slice(1):

// Given string
let givenString = "Hello, World!";

// Remove the first character
let stringWithoutFirstChar = givenString.slice(1);

console.log(stringWithoutFirstChar);

Approach 4: Using ES6 Arrow Functions and slice()

Using the spread operator, you can convert the string into an array, remove the first element, and then join it back into a string by using slice():

Here is an example of remove first character from string using es6 arrow function with slic():

// Given string
let givenString = "Hello, World!";

// Remove the first character
let stringWithoutFirstChar = [...givenString].slice(1).join('');

console.log(stringWithoutFirstChar);
