Add a method to the object literal called countWords(). countWords() should return the number of individual words in the

const myString = { string: "Programming with Treehouse is fun!" countwords:function(){ countWords(myString.length) }

}

mystring.js 
const myString = {
    string: "Programming with Treehouse is fun!"
  countwords:function(){

  }

}

const myString = {
    string: "Programming with Treehouse is fun!",

return this.string.split(" ").length;

  • the method should not call itself
  • the method should return a value
