Not everything is an object. When it comes to functional programming, it’s more to do with the processes that get you from point A to point B than how data and groups of business logic are structured.

JavaScript is a language that’s prone to imperative patterns because of how easy it is to pick up. A lot of developers tend to write their code in a procedural manner — where one blip in the procedure can break the code or create side-effect bugs.

Open browser. 
Start browsing the Internet.
