Why filter() method in js is amazing and essential.

Filter() in js is a method that we used when we want to extract some element based on the condition , it stores those value in a new array.

Important point is that we sent function as an argument in a filter(function) method.

This type is called callbyfunction method.

It replaces bulky for loops into single, expressive line of codes.

True stays, False goes: If the test function returns true (or a truthy value) for an item, that item is pushed into the new array. If it returns false, the item is skipped.
