Overall not bad of an overview and may be useful for someone looking for where to start.

What you should definitely improve about this article is some styling and proofreading. You left in multiple typos, 2 of the sections from overview aren't even in the article and the code snippets have barely any formating and are hard to read.

you said

const add = () => { a + b} ;
Enter fullscreen mode Exit fullscreen mode

there is not even a or b in the param. Also, you open the {, and so you need a return. Otherwise it is going to evaluate a + b and return nothing.

Or just use

const add = (a, b) => a + b;
Enter fullscreen mode Exit fullscreen mode

code readable and highlighted.

Example:

console.log("Hi");
Enter fullscreen mode Exit fullscreen mode
