Use the map Method to Extract Data from an Array | Functional Programming | freeCodeCamp

📽️ **The Power of Transformation**:

In this episode, we explore the transformative `map` method, a tool that empowers us to reimagine each element of our array without altering the original storyline.

🌟 **A Cast of Data**:

Our `watchList` array is a cast of cinematic gems, each with a story and a score. With the `map` method, we spotlight the stars—the titles and ratings—crafting a new array that showcases only the essence of each film.

🔍 **Focused Storytelling**:

Learn with us how to focus your narrative, extracting only the plot points you need to tell your tale. We refine our data into a list of film titles paired with their IMDB ratings, ready for the audience's applause.

For some reason when I was doing this and getting error because of a lack of parenthesis, I couldn't figure out why. I remembered after watching this that someone told me if you are implicitly returning object literal, if the object is not wrapped in parenthesis map() expects the braces to symbolize a function code block so we need to wrap implicitly returned object literals in parenthesis. Or we could use a regular code block with explicit return key word. If anyone is watching and wondering.

I seriously doubt anyone with moderate coding knowledge can do these last 3/4 projects with no help.
