How to use push array method?

The `push()` method in JavaScript is a fundamental array method used to add one or more elements to the end of an array. It is widely used in JavaScript programming when you need to dynamically expand the content of an array.

Basic Usage

Here’s how you can use the `push()` method:

            // Create an empty array
            let fruits = [];

            // Use push() to add elements to the end of the array
            fruits.push("apple");   // Adds "apple" to the end
            fruits.push("banana");  // Adds "banana" to the end
            fruits.push("cherry");  // Adds "cherry" to the end

            // The array now contains ["apple", "banana", "cherry"]
            console.log(fruits); // Output: ["apple", "banana", "cherry"]
        

You can also push multiple elements at once:

            fruits.push("date", "elderberry");

            // The array now contains ["apple", "banana", "cherry", "date", "elderberry"]
            console.log(fruits); // Output: ["apple", "banana", "cherry", "date", "elderberry"]
        

Return Value

The `push()` method modifies the original array and returns the new length of the array. This can be useful when you need to keep track of the array’s size.

Conclusion

The `push()` method is a simple yet powerful way to add elements to the end of JavaScript arrays. It is a fundamental tool for managing dynamic data and building more complex data structures.
