    //      note 1: Splits a string into components by separator, similar to Swift components(separatedBy:).
    //   example 1: componentsSeparatedBy('a,b,c', ',')
    //   returns 1: ['a', 'b', 'c']
    //   example 2: componentsSeparatedBy('a,,b,', ',')
    //   returns 2: ['a', '', 'b', '']
    //   example 3: componentsSeparatedBy('abc', '')
    //   returns 3: ['a', 'b', 'c']
