Write the function calcWordFrequencies$()$ that has a single words parameter. calcWordFrequencies$()$ is called with a string argument containing a list of words separated by spaces. The function should output those words and their frequencies to the console.

Ex: If the function call is:

calcWordFrequencies$("$hey hi Mark hi mark"$)$;

then the console output is:

hey $1$ hi $2$ Mark $1$ mark $1$

Hint: First use the string method split$()$ that splits a string into an array using a delimiter. Ex: words.split$("")$ returns an array containing each word in words. Then place unique words in a map, where the key is the word and the associated value is the word's frequency.
