Learning JavaScript Deeply Using MDN — Need Guidance [closed]

I want to learn JavaScript in depth, and I strongly prefer reading documentation rather than watching video tutorials.

I’ve decided to learn JavaScript mainly from MDN Web Docs, but I’m confused about where to begin:

JavaScript Guide:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide

Learn Web Development → Core → Scripting:
https://developer.mozilla.org/en-US/docs/Learn_web_development/Core/Scripting

My goal is to gain strong conceptual and internal understanding of JavaScript, not just surface-level usage.

My questions:

Which of these two paths should I start with for deep JavaScript knowledge?

In what order should I follow MDN to become really strong in JavaScript?

Is it okay to post learning-path and documentation-based questions like this in this subreddit?

Any guidance from experienced developers would be really helpful.
