    In JavaScript, arrays are used to store multiple values in a single variable. They can be created using various methods depending on the use case.

    Example: Using Array Literal

    The simplest way to create an array is by using square brackets [].

    const fruits = ["Apple", "Banana", "Cherry"];
    console.log(fruits); // Output: ["Apple", "Banana", "Cherry"]
    Copied!

    Using the Array Constructor

    You can create an array using the Array constructor. If a single numeric argument is passed, it creates an array with that length filled with empty slots.

    const arr = new Array(5);
    console.log(arr); // Output: [ <5 empty items> ]
    Copied!

    Using Array.from()

    This method creates a new array from an iterable or with a specified length and mapping function.

    const arr = Array.from({ length: 5 }, (_, index) => index);
    console.log(arr); // Output: [0, 1, 2, 3, 4]
    Copied!

    Using Array.apply()

    You can use Array.apply() along with .map() to create arrays with specific values.
