In this video I explain and show the 3 ways of how to write and execute your JavaScript code. I give a short demo of each and also explain the disadvantages of each.

👩🏻‍💻 Where to write and execute JavaScript:
► 1) Writing and executing JavaScript directly in the Browser Console is the simplest way to get started. It's practical when you want to try something out, but not an option for real programming. Find out why in the video.
► 2) The second option writing JavaScript code in the index.html file (called inline script) is better, but has some disadvantages in structuring and keeping HTML/CSS apart from your logic.
► 3) The third and last way to write JavaScript code, is writing the code in a separate JavaScript file and linking this file in the HTML file. This is the way to go, because it is clean and practical when your application gets bigger.

👩🏻‍💻 Simple Text Editor vs. Special Code Editor:
I also explain and show you the advantages of writing your JavaScript code in a special code editor instead of writing it in a simple text editor. One example is the highlighting of keywords or syntax error detection, which helps a lot in programming.

👩🏻‍💻 Understand file structure in real projects and file path
