points
In JavaScript it is possible to remove the first n characters from the string in the following way.
1. Using String slice() method
// ONLINE-RUNNER:browser;
// remove first n characters from string
function removeFirstChars(text, n) {
return text.slice(n);
}
console.log( removeFirstChars('12345', 0) ); // 12345
console.log( removeFirstChars('12345', 1) ); // 2345
console.log( removeFirstChars('12345', 2) ); // 345
console.log( removeFirstChars('12345', 3) ); // 34
console.log( removeFirstChars('12345', 4) ); // 5
// below results are empty, that's why we compare them to ''
console.log( removeFirstChars('12345', 5) === '' ); // true
Note:
We can achieve the same results using:
- String
substring()method- String
replace()method
