  • JavaScript provides a rich set of array methods that empower developers to manipulate and work with arrays efficiently. These methods simplify common tasks, making code more concise and readable.
    Mutating Methods:
    push(): Adds elements to the end of an array.
    pop(): Removes and returns the last element.
    shift(): Removes and returns the first element.
    unshift(): Adds elements to the beginning.
    Combining and Extracting Methods:
    concat(): Combines arrays, creating a new one.
    slice(): Extracts a portion of an array without modifying the original.
    Modification Methods:
    splice(): Adds or removes elements at a specified index.
    indexOf(): Finds the index of a specified element.
    Iteration Methods:
    forEach(): Executes a function for each array element.
    map(): Creates a new array by applying a function to each element.
    These methods provide a powerful toolkit for array manipulation, allowing developers to perform diverse operations such as adding, removing, extracting, and transforming elements in an array with ease. Understanding these methods is crucial for effective JavaScript programming.
