The replace() method in JavaScript is used to search a string for a value or any expression and replace it with the new value provided in the parameters. The original string is not changed by this method.

Syntax:

string.replace(searchVal,newVal)

Parameter: This method accepts two parameters. 

  • searchVal: It is the value that we want to replace in the existing string
  • newVal: It is the new value that is to be put in the place of searchVal.

Return Value: This method returns a new string where the desired values have been replaced.

Example 1: In this example, we will use the replace() method to replace a character from the original string but the replace method here does not replace the characters which are in lowercase.

Javascript

let stringReplace = "Geeks for geeks is a great platform to learn Javascript";
let result = stringReplace.replace(/Geeks/, "GFG");
console.log('New string: ' + result);

                    

Output
New string: GFG for geeks is a great platform to learn Javascript

Example 2: In this example, the replace() method replaces the words completely irrespective of their case.

Javascript

let stringReplace = "Geeks for Geeks is a great platform to learn Javascript";
let result = stringReplace.replace(/Geeks/gi, "GFG");
console.log('New string: ' + result);

                    

Output
New string: GFG for GFG is a great platform to learn Javascript
