- Writing tests with Chai's expect method
- The goal is to create a function to evaluate a move title and make sure the words are capitalized
- First write a test to confirm the movie title is a string. Then write the code and check it with the test
- Then break the process down into small steps, check one letter, then check one word
- Write a test to check if the first letter in the word is capitalized
- Then write a function and a step to capitalize the a letter
- Then the first letter of a word.
- Build logic for changing one word then put it into a loop:
- Split each word in the string
- Rejoin each word back into the title
