By the end of this project you will have created and used a function in JavaScript. You will use the Notepad++ editor to write both internal and external JavaScript functions and the code to call them from within an HTML file. Through hands-on practice you will compare methods and functions and look at built-in functions versus user-defined functions. Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.
