How to use Splice Method In Javascript
The `splice()` method in JavaScript can be used to store an object inside an array by specifying the starting index and deleting zero elements, then inserting the object.
Syntax:
arr.splice(index, 0, objectName)
Example: In this example, we define an array myArray with objects. It adds two new objects, newObj1 and newObj2, to the end of the array using the splice() method.
Javascript
const myArray = [ { name: "Rahul", language: "HTML" }, { name: "Nikita", language: "Javascript" },];// Objects to be addedconst newObj1 = { name: "Virat", language: "React" };const newObj2 = { name: "Megha", language: "Redux" };myArray.splice(myArray.length, 0, newObj1, newObj2);console.log(myArray); |
Output
[
{ name: 'Rahul', language: 'HTML' },
{ name: 'Nikita', language: 'Javascript' },
{ name: 'Virat', language: 'React' },
{ name: 'Megha', language: 'Redux' }
]
