Slicing A String

The slice method

The slice method is commonly used in simple functions and coding challenges. It returns a substring of the string specified by its argument list.

The easiest way to remember the parameter list of slice is:

str.slice(firstIndexInString)

or

str.slice(firstIndexInString, firstIndexAfterString)

The first argument of slice specifies the position of the first character of the substring. The second argument is optional. When it is missing, slicing happens until the end of the string. When it is specified, it points at the first character after the sliced substring.
