Remove characters from a string contained in another string with JavaScript?

JavascriptWeb DevelopmentObject Oriented Programming

Let’s say the following are our two strings −

var originalName = "JOHNDOE";
var removalName = "JOHN"

We need to remove the second string from first. For this, use replace() along with reduce().

Example

const removeCharactersFromAString=
(removalName,originalName)=>removalName.split('').reduce((obj,v)=>obj.replace(v,''),originalName);
var originalName = "JOHNDOE";
var removalName = "JOHN"
console.log(removeCharactersFromAString(removalName,originalName));

To run the above program, you need to use the following command −

node fileName.js.

Here, my file name is demo93.js.

Output

This will produce the following output −

PS C:\Users\Amit\JavaScript-code> node demo93.js
