my_str.substring(start, [end])
start An integer that indicates the position of the first character of my_str used to create the substring. Valid values for start are 0 through String.length - 1. If start is a negative value, 0 is used.
end An integer that is 1+ the index of the last character in my_str to be extracted. Valid values for end are 1 through String.length. The character indexed by the end parameter is not included in the extracted string. If this parameter is omitted, String.length is used. If this parameter is a negative value, 0 is used.
A string.
Method; returns a string consisting of the characters between the points specified by the start and end parameters. If the end parameter is not specified, the end of the substring is the end of the string. If the value of start equals the value of end, the method returns an empty string. If the value of start is greater than the value of end, the parameters are automatically swapped before the function executes and the original value is unchanged.
