Array in Javascript...

An array in JavaScript is a special variable that can hold multiple values in a single variable, instead of storing just one value like a normal variable does.

Basic Example:

let Phones = ["Vivo", "Oppo", "Samsung"];

console.log(fruits[0]); // Vivo
console.log(fruits[1]); // Oppo
console.log(fruits[2]); // Samsung

Key Points:

• Index starts at 0 - First item is array[0], not array[1]

• Can hold any data type - Numbers, strings, booleans, objects, even other arrays

• .length - Gives the total number of items

• Dynamic size - You can add/remove items anytime

Mixed Array:

A mixed array is just an array that stores different data types together in a single array, instead of only numbers or only strings.

Example:

let mixedArray = ["Messi", 22, true, ["Tamil", "English"], { city: "Chennai" }];
