Methods which simplifies work with javascript
Most of the methods that can work on arrays, strings, and objects used to simplify our coding works, mostly loops. A few of those for quick reference with examples.

.split
It split a string into array of substrings, and returns a new array.
We have many predefined ways to make work simple and efficient, but how complex and different can use those ways is upto us. Keep on try new way of using based on scenario to take ready-in advantage to required extent.
