In ECMAScript Specification, the functions aren’t on the type list. Intuitively, function values have a specific behaviour, that is different from values that are numbers - so isn’t it a type? JavaScript refers to functions as a sub-type of the object type - sometimes refers to them as a callable object.
Conclusion: Functions are sort of type, but a sub-type - not a top level type…

13 Useful JavaScript Developer Tools for Writing High-Quality Code
Today I’m going to show you 13 well-know and popular tools to write better and cleaner JavaScript code.
These are tools that I’m using right now on my JavaScript developer journey.
So if you want to improve the quality of your projects, this list is for you.
1. npm
NPM is a package manager for Nodejs with hundreds of thousands of packages, and you can use it for front-end development too.
The main purpose of using NPM is automating dependency and package management. If you use a library by importing it directly without using NPM, you will do it every time you want to update the library. It’s a heavy time-consuming as your project grows. Instead of spending time on invaluable tasks, install NPM once and it will take care of all of them for you.
2. JSFiddle
When I come up with a new idea for my projects, I’ll test it out on JSFiddle to see how everything goes. For a quick test before adding things to the real project, JSFiddle is the perfect solution.
