In this article, we would like to show you how to remove prefix from string in JavaScript.
Quick solution:

const text = 'ABCD';2
3
const result1 = text.slice(2); // omits the first two characters4
const result2 = text.substring(2); // omits the first two characters5
const result3 = text.replace(/^AB/, ''); // replaces "AB" only if text starts with it6
7
console.log(result1); // CD8
console.log(result2); // CD9
console.log(result3); // CD
In this example, we use String slice() method to omit the first two letters from the text.
