Use the blog to sharpen answers, review weak areas, and move from basics to mock-style prep without guessing what to read next.
Resume Prep
Jump back into the roadmap you already started, or use the article filters below to practice a specific topic.
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.
A practical, interview-focused guide to the JS event loop: call stack, Web APIs, task queues, microtasks vs macrotasks, and common trick questions with real examples.
A deep, interview-ready guide to TypeScript types vs interfaces: extension, unions, intersections, declaration merging, and practical patterns for real codebases.
