Remove first character from a string in JavaScript

This post will discuss how to remove the first character from a string in JavaScript.

Since strings are immutable in JavaScript, we can’t in-place remove characters from it. The idea is to create a new string instead. There are three ways in JavaScript to remove the first character from a string:

1. Using `substring()` method

The substring() method returns the part of the string between the specified indexes or to the end of the string.

let str = 'Hello';

str = str.substring(1);

console.log(str);

Output: ello

You can easily extend the solution to remove the first n characters from the string.

let str = 'Hello';

let n = 3;

str = str.substring(n);

console.log(str);

Output: lo

2. Using `slice()` method

The slice() method extracts the text from a string and returns a new string.

let str = 'Hello';

str = str.slice(1);

console.log(str);

Output: ello

This can be easily extended to remove first n characters from the string.

let str = 'Hello';

let n = 3;

str = str.slice(n);

console.log(str);

Output: lo

3. Using `substr()` method

The substr() method returns a portion of the string, starting at the specified index and extending for a given number of characters or until the string’s end.

let str = 'Hello';

str = str.substr(1);

console.log(str);

Output: ello

Note that substr() might get deprecated in the future and should be avoided.

That’s all about removing the first character from a string in JavaScript.
