β push
β The "push" method Add a new item to an array.
for example β©
β ["computer science", "math", "bio", "physics"]; β this is an array & stores some methods but if you want to add a new (element) to this array use the "push" method.

let book = ["CS", "Math", "Bio"]; (this is a array)
βThe splice() method removes a particular element in an array.
You can use the splice() method to remove the book names from the 'book'!
let book = ["CS", "Math", "Bio"]; (this is a array)
