What is the use of the String.trim() Method in JavaScript ?
The String.trim()
method in JavaScript is used to remove whitespace (spaces, tabs, and newline characters) from both ends of a string. It returns a new string with the leading and trailing whitespace removed.
Example: Here, the original string has extra spaces at the beginning and end. The trim()
method is called on that string, resulting in a new string without the leading and trailing spaces.
Javascript
const stringWithWhitespace = ' Hello, World! ' ; const trimmedString = stringWithWhitespace.trim(); console.log(trimmedString); // Output: 'Hello, World!' |
Output
Hello, World!
