Array Methods - push, pop, unshift, shift
Let's learn about methods for managing elements within an array.
array.push
The push method adds new items to the end of an array. It's like adding a card to the top of a deck of cards.
Example of push method
const fruits = ['apple', 'banana'];
fruits.push('cherry');
console.log(fruits); // Prints ["apple", "banana", "cherry"]
array.pop
The pop method removes the last item from an array and returns that item. It's like taking the top card from a deck of cards.
Example of pop method
const fruits = ['apple', 'banana', 'cherry'];
const lastFruit = fruits.pop();
console.log(lastFruit); // Prints "cherry"
console.log(fruits); // Prints ["apple", "banana"]
array.unshift
The unshift method adds new items to the beginning of an array. It's like inserting a card at the bottom of a deck of cards.
Example of unshift method
const fruits = ['banana', 'cherry'];
fruits.unshift('apple');
console.log(fruits); // Prints ["apple", "banana", "cherry"]
array.shift
The shift method removes the first item from an array and returns that item. It's like taking the bottom card from a deck of cards.
Example of shift method
const fruits = ['apple', 'banana', 'cherry'];
const firstFruit = fruits.shift();
console.log(firstFruit); // Prints "apple"
console.log(fruits); // Prints ["banana", "cherry"]
