Slasher Intermediate explanation has incorrect statement regarding slice()

[raisedadead]

Refers : freeCodeCamp/freeCodeCamp#9501

by @wiseleo:

Someone apparently copied the explanation from splice.

Modify the array with slice() and return it.

Slice does not modify arrays.

The slice() method returns a shallow copy of a portion of an array into a new array object. - Source: MDN

The entire explanation is problematic:

• This solution uses the slice() function. OK
• The argument howMany is the number of elements to be removed skipped since beginning of array starting with arr[0].
• Modify the array with slice() and return it. Return the remaining array without modifying original array
