Common Array methods in JavaScript that modify the array in place
The following are the common array methods in JavaScript that modify the original array instead of returning a new one: 1. pop(): Removes and returns the last element from an array. Example: myArray.pop(); 2. push(): Adds one or more elements to the end of an array and returns the new length of the array. Example: myArray.push(element1, element2); 3. shift(): Removes and returns the first element from an array. Example: myArray.shift(); 4. unshift(): Adds one or more elements to the beginning of an array and returns the new length of the array. Example: myArray.unshift(element1, element2); 5. splice(): This is a versatile method that can be used to: Remove elements from an array (splice(start, deleteCount)) Add elements to an array (splice(start, 0, element1, element2)) Replace elements in an array (splice(start, deleteCount, element1, element2)) Example: myArray.splice(2, 1); // Removes one element at index 2 myArray.splice(1, 0, 'newElement'); // Adds 'newElement
