How to remove a specific property from an object ?

Question

I have a user object having the following properties:

let user = {

  name: "john",

  pin: 45,

  gender: "Male",

  updated: "Yes",

  active: true,

};

Now I want to remove pin completely from the object. So how will I do this in Javascript ?

Answer 1

In order to remove a property from an object in javascript, we use the delete keyword.

Suppose you have the following user object:

let user = {

  name: "john",

  pin: 45,

  gender: "Male",

  updated: "Yes",

  active: true,

};

Now if you want to remove the pin property from the user object, you do:

delete user.pin;

when you log the user object:

console.log(user)

Your resulting user object will look like this:

{name: "john", gender: "Male", updated: "Yes", active: true}
