What are the differences between JavaScript's Array.push() and Array.pop() methods?
Benjamin C

JavaScript'sArray.push() andArray.pop() are two methods used to manipulate the elements of an array. Here are the differences between them: 1. Functionality: -Array.push(): - Adds one or more elements to the end of an array. -Array.pop(): - Removes the last element from the end of an array and returns that element. 2. Return values: -Array.push(): - Returns the new length of the array after adding the elements. -Array.pop(): - Returns the removed element. 3. Modifying the array: -Array.push(): - Modifies the original array by adding elements to the end. -Array.pop(): - Modifies the original array by removing the last element. 4. Adding elements: -Array.push(): - Accepts one or more arguments and adds them as separate elements to the end of the array. -Array.pop(): - Does not accept any arguments since it always removes the last element from the array. 5. Order of operations: -Array.push() andArray.pop(): - Follow the "Last In, First Out" (LIFO) principle. Elements added withpush() will be retrieved in the reverse order with subsequentpop() calls. Here's an example illustrating the differences:

const numbers = [1, 2, 3];

console.log(numbers.push(4, 5)); // Output: 5 (new length)
console.log(numbers); // Output: [1, 2, 3, 4, 5]

console.log(numbers.pop()); // Output: 5 (removed element)
console.log(numbers); // Output: [1, 2, 3, 4]

In summary,Array.push() adds one or more elements to the end of an array and returns the new length, whileArray.pop() removes the last element from the end of an array and returns that element.push() modifies the original array by adding elements, whereaspop() modifies the original array by removing the last element. Remember thatpush() accepts one or more arguments to add as separate elements, whilepop() does not accept any arguments.
