CSS Performance: contain, content-visibility, and Rendering Cost Control
How to reduce rendering cost with modern CSS tools: containment, content-visibility, and avoiding expensive effects that trigger heavy paint/layout.

Start with JavaScript Core and build your path from basics to mock review.
Basics build confidence, practice sharpens answers, and the roadmap keeps you moving toward the next interview topic.
If you want a guided path (instead of random reading), pick a roadmap. Each one is ordered top-to-bottom.
Event loop, closures, this, hoisting, async, and the fundamentals interviews test.
Types vs interfaces, narrowing, generics, utility types, and practical TS patterns.
Rendering, hooks, state, effects, performance, and common production patterns.
Semantics, layout, flexbox/grid, responsive design, accessibility, modern CSS.
The first lesson in each roadmap — great if you want a clean entry point.
