How to Remove First 2 Letters from String in Javascript

In this tutorial, you will learn how to remove first 2 letters from string in javascript. Since a string is built with the help of multiple characters such as letters, numbers as well as special characters, the position of the first 2 letters varies.

There are numerous ways to remove the first 2 letters from a string. We are going to create a custom function that involves the usage of the match() method and for loop to find the first 2 letters in the string. Later, we will use replace() method to get rid of the first 2 letters.

In the following example, we have one global variable that holds a string. Upon click of a button, we will remove the first 2 letters of the string and display the result on the screen.  Please have a look over the code example and the steps given below.


  • We have 3 elements in the HTML file (div, button, and h1). The div element is just a wrapper for the rest of the elements.
  • The innerText for the button element is “Get” and for the h1 element, it is “Result”.
  • We have done some basic styling using CSS and added the link to our style.css stylesheet inside the head element.
  • We have also included our javascript file script.js with a script tag at the bottom.
<!DOCTYPE html>
<html lang="en">

  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <meta http-equiv="X-UA-Compatible" content="ie=edge">
  <link rel="stylesheet" href="style.css">


  <div class="container">    

  <script src="script.js"></script>

.container {        
    text-align: center;

button {
  margin-top: 10px;
  padding: 10px 20px;


  • We have selected the button element and h1 element using the document.querySelector() method and stored them in btnGet and output variables respectively.
  • We have attached a click event listener to the button element.
  • We have a global variable myString which holds a string as its value.
  • In the event handler function, we are calling the removeLetters() method and passing myString and 2 as parameters. This method will be responsible for removing the first 2 letters and returning the rest of the string.
  • In the removeLetters() method, we are using for loop to loop through all the characters. Inside the loop, we are checking whether a character is letter or not using the match() method which takes /[a-zA-Z]/g as a regex pattern. As a result, we are getting an array of letters or null which we are storing in the isLetter variable.
  • We are skipping the replacement part using the continue statement if the character is not a letter.
  • Further, we are calling the replace() method and passing it 2 parameters; char and an empty string. As a result, it will remove first 2 letters from the string.
  • The final string is stored in the newStr variable.
  • We are getting out of the loop using the break statement after removing the first 2 letters.
  • The returned string is stored in the result variable and we are displaying the result in the h1 element using the innerText property.
let btnGet = document.querySelector("button");
let output = document.querySelector("h1");

let myString = "123 Hello world";

btnGet.addEventListener("click", () => {
  let result = removeLetters(myString, 2);
  output.innerText = result;

function removeLetters(str, num) {
  let newStr = str;
  let count = 0;
  for (const char of str) {
    let isLetter = char.match(/[a-zA-Z]/g);
    if (!isLetter) continue;

    newStr = newStr.replace(char, "");
    if (count == num) break;
  return newStr;
