This exercise expects you to return a sentence.
You must bear in mind that each word needs a space.
For example:
const myNoun = “dog”;
const wordBlanks = "My " + myNoun;
You can see how after the word 'My ’ there is a space. You must take that into account for each word.
A good habit to get into is to use console.log when you’re not sure why your code isn’t working. You can use this to show what your variables/functions etc are returning so you can see more easily what might be going wrong.
If you console.log(wordBlanks) at the bottom of your code, you’ll see immediately what is going wrong.
