Mixed Arrays

The mixed arrays in JavaScript can contain elements of multiple data types stored at contiguous memory location with same name that can be accessed using the indexing syntax.

Example: The below code is the practical implementation of the mixed arrays in JavaScript.

Javascript

const mixedArr = 
[
    [1, 2, 3],
    "w3wiki",
    23,
    {
        cricketer: "Virat Kohli"
    }
];
 
console.log("Array element: ", mixedArr[0]);
console.log("String element: ", mixedArr[1]);
console.log("Number element: ", mixedArr[2]);
console.log("Object element: ", mixedArr[3]);

Output

Array element:  [ 1, 2, 3 ]
String element:  w3wiki
Number element:  23
Object element:  { cricketer: 'Virat Kohli' }

Types of Arrays in JavaScript

A JavaScript array is a collection of multiple values at different memory blocks but with the same name. The values stored in an array can be accessed by specifying the indexes inside the square brackets starting from 0 and going to the array length – 1([0]…[n-1]).

A JavaScript array can be classified into multiple types:

Table of Content

Numeric Array
String Array
Array of Arrays (2D Arrays)
Array of Objects
Mixed Arrays
Array with empty values
