Reverse the words and capitalize them

Write a function reverseAndCapitalize(text) that returns the words of the string text in reverse order, and every word starts with a capital letter: 'India is great' becomes 'Great Is India'.

• Words in text are separated by one or more spaces. There can be spaces at the start and at the end. A word is any group of characters without spaces, so it can contain ' or -.
• In every word the first character becomes upper case and all other characters become lower case: 'wORLD' becomes 'World'. Change the letter case with toUpperCase() and toLowerCase(); a digit stays as it is.
• The letters inside a word keep their order. Only the order of the words changes.
• In the result, words are separated by exactly one space, with no spaces at the start or the end.
• For an empty string or a string of spaces return ''.

You can split the string into words, reorder them and join them back.
