Normal array de-weight--using filter

Filter () Basic syntax:

Arr.filter (Callback[,thisarg])

Callback the function used to test each element of an array. Calling when using a parameter (Element,index.array) returns true to preserve the element (test pass), false is not preserved.

Three parameters passed in when the callback is invoked:

1. The value of the element, the index of the 2 element, and the 3 traversed array

Thisarg is optional. The value to use for this when executing callback.

Filter does not change the original array.

The range of elements traversed by the filter is determined before the first call to callback. Elements that are added to the array after the call to filter are not traversed by the filter. If the already existing elements are changed, the value they pass into the callback is the value that the filter iterates over to their moment. Elements that have been deleted or that have never been copied are not traversed.

For general arrays, use the filter to redo the example:
