Javascript String Replace: How to Replace String in JavaScript

Javascript String replace() is an inbuilt function that returns the new string with some or all matches of the pattern replaced by the replacement. The pattern can be the string or the RegExp or Regular Expression, and the replacement can be the string or the function to be called for each match. If the pattern is a  string, only the first occurrence will be replaced.

Javascript String replace()

The javascript string replace() method does not change the String object it is called on. It only returns a new string if we want to perform a global search and replace, including the g switch in the regular expression.


The syntax of the Javascript string replace() method is the following.

string.replace(searchValue, newValue)

#javascript #javascript string replace #regexp #regular expression
