11 important array methods in JavaScript
Arrays are one of the most used elements in JavaScript. Today I’m covering 11 arrays methods that will help you work more effectively.
1. join() method : this method joins all the elements of the array and returns a string
2. push() method : this method adds a specific element at the end of the array
3. pop() method : this method removes the last element of an array
4. sort() method: this method arranges all the elements of the array in an ascending of descending way
5. forEach() method: this method goes through the entire array and does something to each element of the array without returning anything
6. map() method: this method is similar to the forEach method but the difference is that this map() method returns a new array after applying something to all the elements of that array
7. slice method (): this method cuts a certain part of an array and returns that part in a new array
8. shift method () : this method removes the first element of an array
9. unshift method (): this method adds an element at the beginning of the array
10. indexOf method (): this method checks for the location of a specific element in the array and returns its position or -1 if the element is not found
11. Find method (): this method goes through the array and tries to find a specific element, if found it returns that element, or that first element that matches the search , if there is no element, it returns undefined .
