JavaScript is a scripting or programming language that allows you to implement complex features on web pages — every time a web page does more than just sit there and display static information for you to look at — displaying timely content updates, interactive maps, animated 2D/3D graphics, scrolling video jukeboxes, etc. — you can bet that JavaScript is probably involved. It is the third layer of the layer cake of standard web technologies, two of which (HTML and CSS) we have covered in much more detail in other parts of the Learning Area. see more
Simply , you'll need a code editor , I suggest using visual studio code or replit. In your visual studio code , create a file call index.js , you can neither name it stuff.js or any name but you i'll have to put the js dot at the end. Or in replit , make a new repl and choose the node.js, then give your repl a name and then you are good to go.
