In this post, I show you how to remove Object from an Array of Objects in JavaScript. This is a common requirement while coding in JavaScript. I hope this post helps you.

Remove Object from an Array of Objects in JavaScript

// using Object Literals var user1 = { id : 1, firstName : 'Ramesh', lastName : 'Fadatare', emailId : 'ramesh@gmail.com', age : 29 } var user2 = { id : 2, firstName : 'John', lastName : 'Cena', emailId : 'john@gmail.com', age : 29 } // we have an array of objects, we want to remove one object using only the id property var users = [user1, user2]; console.log('Before removing object from an array -> ' + JSON.stringify(users)); // get index of object with id:37 var removeIndex = users.map(function(item) { return item.id; }).indexOf(37); // remove object users.splice(removeIndex, 1); console.log('After removing object from an array -> ' + JSON.stringify(users));

Output:

Before removing object from an array -> [{"id":1,"firstName":"Ramesh","lastName":"Fadatare","emailId":"ramesh@gmail.com","age":29}, {"id":2,"firstName":"John","lastName":"Cena","emailId":"john@gmail.com","age":29}] After removing object from an array -> [{"id":1,"firstName":"Ramesh","lastName":"Fadatare","emailId":"ramesh@gmail.com","age":29}]

From the above output, the first user object with id = 1 has deleted from Array.

For the best learning experience, I highly recommended that you open a console (which, in Chrome and Firefox, can be done by pressing Ctrl+Shift+I), navigate to the "console" tab, copy-and-paste each JavaScript code example from this guide, and run it by pressing the Enter/Return key.
