Reverse Every Word in a String

/* Write a JavaScript function reverseWordsInString(str) that accepts as a parameter a string and reverses
the characters of every word in the string but leaves the words in the same order. Words are considered
to be sequences of characters separated by spaces. Write a JavaScript program reverseWords.js that prints
on the console the output. */
