It’s awesome! It means you don’t need to remember all the methods on an object. It makes exploring new frameworks very easy. It also means you don’t have to press all.the.keys().
VSCode will try to guess what it thinks you’re about to type. So if you go to a new file, and type ‘fun’, VSCode will offer you ‘function’, and you can just press tab and it will complete ‘fun’ to ‘function’.
When we are playing with a new framework, or perhaps another member of the team has created an Object for us, we want to explore what properties we have. IntelliSense makes this very easy. We create a new instance of the object, and simply press ‘.’ and VSCode will present us with all the functions as demonstrated in this handy gif from the Official VS Code Docs on IntelliSense
