I began understanding the little deeper into the JavaScript concepts. One such concept is destructive and non destructive methods for the array.
What is an array ? . Array is linear data structure and it is heterogeneous in JavaScript. Array's methods can be split into two types destructive and non destructive methods.
Non Destructive Method :- A method which returns the new array without modifying the original array. They behave differently that they don't make any changes to the original array provided and returns the new array in each time.
Few example explored
Destructive Methods :- A method which mutates the original array. A provided array will gets modified on the destructive method operation.
Most of the time non destructive methods always come in handy. This is pretty much concept about the array types :)
