JavaScript Glossary - Lesson #27

JavaScript String .trim() Method

This method removes whitespaces from the start and end of the calling string. It removes spaces, tabs, no break spaces etc. It returns a new string stripped of whitespaces from both sides of the array.

js
""   hello world   "".trim()
// hello world

Note the method is also case sensitive

js
const trimmedSent = oldString.trim()

A new string object without whitespace at both ends. It doesn’t change the calling string.
