Learn React the easiest and fastest way with Explainer Captain Yalco's rich and solid course!

This course is a full-stack level frontend project course that focuses on implementing Notion from start to finish using Vanilla JavaScript, going beyond simple UI cloning to deeply understand the internal operating principles. You'll implement all the core features of a real note-taking app using vanilla JS, including sidebar tree, nested document creation, auto-save, routing, trash, favorites, search modal, settings modal, theme switching, Export/Import, keyboard shortcuts, responsive layout, drag resize, and more.
