What is Array ?

An array is a special variable, which can hold more than one value.

let newArray = [12, "Koushik", null, false, 100]

All Array Methods In JavaScript

I will Discuss about some of them.

How to Create an Array ?

let newArray = [1, 2, 3, 4, 5];

let newArray =new Array("Koushik", "Saha", true);

Array Methods :

For output of methods, you have to run below codes in your code editor, and this is best practice.

1. Array Length -

let newArray = [1, 2, 3, 4, 5];
console.log(newArray.length);

it is a array property. Not a method.

2. Array.Push( ) -

This method adds elements at the end of an array.

let newArray = [ ];
newArray.push(10);
newArray.push(12, "Koushik");
console.log(newArray);

3. Array.Pop( ) -

This method removes elements from the end of the array.

let newArray = [1, 2, 3, 4];
newArray.pop();
console.log(newArray)

4. Array.Shift( ) -

It is the opposite of array.pop(). It removes elements from the front of the array.

let newArray = [1, 2, 3, 4];
newArray.shift();
console.log(newArray)

5. Array.UnShift( ) -

It is the opposite of array.push(). It add elements from the front of the array.

let newArray = [1, 2, 3, 4];
newArray.unshift();
console.log(newArray)

# How to Grab Elemnts from an Array :

Array Index start from 0.

let newArray = [1, 2, 3, 4];

// Grabing first element.😎
console.log(newArray[0]);

// Grabing second element.😎
console.log(newArray[1]);

// Grabing third element.😎
console.log(newArray[2]);

// Grabing last element.😎
console.log(newArray[newArray.length - 1]);
