10 Must-Know Array Functions in JavaScript for Better Coding | Salam Aslam

Описание: Arrays are a fundamental data structure in programming, and they are used to store collections of values or data. JavaScript provides several built-in methods for working with arrays that can help make your code more efficient and effective.

push()
The push() method adds one or more elements to the end of an array. This can be useful when you want to add a new element to an array without having to specify the index where it should be inserted.

pop()
The pop() method removes the last element from an array and returns that element. This can be useful when you want to remove an element from an array without having to specify the index where it is located.

delete
The delete operator is used to remove a specific element from an array, but it does not change the length of the array. This means that the index of the deleted element becomes empty, but the other elements remain in the same position.

sort()
The sort() method is used to sort the elements of an array in ascending or descending order. By default, the sort() method sorts the elements in ascending order.

reverse()
The reverse() method is used to reverse the order of the elements in an array. This can be useful when you want to display the elements of an array in reverse order.

splice()
The splice() method is used to add or remove elements from an array. This can be useful when you want to insert new elements at a specific index, or remove elements from a specific index.

Custom Index for Loop Push
This method is a custom approach to using the push() method to add elements to an array. It involves using a for loop to iterate through an array and add elements to it. This can be useful when you want to add a large number of elements to an array in a specific order.

By understanding the basics of these array methods, you can make your code more efficient and effective, and work with arrays more effectively.
