Answer 2

You use Javascript in .js files linked in HTML with script tags. Javascript just allows you to use an actual programming language to manipulate behavior of the web page.

Answer 6

You have learned 99% of JS. You is da real hero!

The main uses of JS in a website are

1. For interactivity:
Dropdowns, carousels, spinners, modals etc
Most designer-developers use pure (vanilla) js or small libraries like jquery, bootstrap etc

2. For single page applications
These are web apps that load all their necessary content on first page load. Further navigation will not cause a page reload. Advanced libraries/framework are usually used e.g Angular, React, Vue, Ember etc.

3. Server side language
With the advent of Node.js and Deno.js, JavaScript can also be used to handle web requests and pre-process responses just like PHP.

You might want to rethink your location on the roadmap. There are many areas you might have not paid attention too like ES 2015 syntax: promises, arrow functions, symbols, typed arrays etc

You might also look into unit testing, machine learning, game development etc.
