What is an Array in Javascript with explaination ?

October 16, 2024

Creating Arrays :
 

  • Using Array Literal Notation

    let fruits = ["apple", "banana", "cherry"];

  • Using the Array Constructor

    let fruits = new Array("apple", "banana", "cherry");
     

    Accessing Array Elements
     

    You can access elements in an array using their index. Note that array indices are zero-based.

    let fruits = ["apple", "banana", "cherry"]; console.log(fruits[0]); // Output: apple console.log(fruits[1]); // Output: banana

    Modifying Array Elements

    You can modify elements directly by accessing their index.

    let fruits = ["apple", "banana", "cherry"]; fruits[1] = "blueberry"; // Changing 'banana' to 'blueberry' console.log(fruits); // Output: ["apple", "blueberry", "cherry"]
