JavaScript Learning GuideFrom Zero to Vue 3

A structured course for college students — build real foundations so you can command AI-era frontend development

🧱

Fundamentals

Variables, control flow, functions, arrays & objects, the DOM and events — reading code and building interactions is where everything starts.

🧠

Closures, this, prototypes, async and network requests — interview staples, and the key to understanding frameworks and AI-generated code.

🚀

Tooling, browser storage, debounce & throttle, working effectively with AI, and the road that leads to Vue 3.

The guide is organized in three progressive tiers. Work through them in order:

Stage	Content	Goal
Fundamentals	Syntax, functions, arrays & objects, DOM, events	Build interactive web pages on your own
Key Concepts	Scope, closures, this, prototypes, async, fetch	Read other people's (and AI's) code; handle interviews
Beyond the Basics	Tooling, storage, common techniques, AI collaboration	Entry-level readiness for real projects; a bridge to Vue 3

Type out every code sample yourself. Understanding it is not the same as being able to write it — muscle memory matters.
Finish each section's exercises before moving on. Every exercise ships with a collapsible reference answer: attempt first, compare after.
Use AI well, but don't let it learn for you. Having AI explain code, help you debug, or quiz you is great; copy-pasting AI answers into assignments only hurts you — interviewers will ask you to modify code on the spot. See Learning with AI.
Look up every word you don't know. MDN (developer.mozilla.org) is the authoritative frontend reference — make consulting docs a habit.

After finishing this guide, you should be able to:

Independently build a static project with form validation, list rendering, and API requests;
Read and modify unfamiliar JS code, and explain what it does;
Answer classic interview questions: What is a closure? What does this point to? What problem do Promises solve?
Enter Vue 3 with the right knowledge structure in place.
