Why did we have to use the split(' ') in the function instead of just .length like we did here?

const myString = { string: "Programming with Treehouse is fun!", countWords: function(){ const wordArray = this.string.split(' '); return wordArray.length; } }

var numWords = myString.countWords();

myString.characters = myString.string.length;

split() returns an array. In this case it splits the string into words using a space (' ') as an argument.

string.length returns the number of characters in the string.
