JavaScript - Delete Character at a Given Position in a String

Last Updated : 21 Nov, 2024

These are the following ways to Delete Character at a Given Position in a String:

1. Using slice() Method

The slice() method allows you to extract portions of a string. By slicing before and after the target position, you can omit the desired character.

JavaScript

let str = "Hello GFG";
let idx = 5;

let res = str.slice(0, idx) + str.slice(idx + 1);
console.log(res);

Output

HelloGFG

2. Using substring() Method

The substring() method works similarly to slice, but does not support negative indices.

JavaScript

let str = "Hello GFG";
let idx = 5;

let res = str.substring(0, idx) + str.substring(idx + 1);
console.log(res);

Output

HelloGFG

3. Using Array Conversion

Convert the string into an array of characters, remove the character at the desired position using splice, and join the array back into a string.

JavaScript

let str = "Hello GFG";
let idx = 5;

let arr = str.split(""); 
arr.splice(idx, 1); 
let res = arr.join("");
console.log(res);

Output

HelloGFG
