Data. Systems.Algorithms.
DSA here means all three — not just data structures and algorithms. Pointers gliding, packets crossing the wire, a scheduler switching context. Press play and watch the idea unfold.
Check every pair — two nested loops over the array.
Never stop at the first answer.
Every problem carries its approaches side by side — the obvious brute force and the sharp optimization. Jump between them in a tap and watch the time and space complexity fall, so you learn the why, not just the trick.

Chai Visual teaches each topic the same way — by animating it. Jump straight in.
Animated, step-by-step walkthroughs from two pointers to dynamic programming. Brute force first, then the optimized trick — always with the why.
Object-oriented design taught with animated UML — class & sequence diagrams that build themselves, plus the theory behind every pattern.
A full visual course — from a single fetch() down to bits on the wire and back up through TCP, DNS, HTTP and TLS. Every step illustrated, so the network stops being a black box.
A full visual course — processes, scheduling, concurrency, virtual memory and file systems, explained the way a working engineer needs them. Every concept illustrated, from a system call down to the kernel.
A plan for the days you actually have.
Name any subject — DSA, JavaScript, Docker, system design — and get a syllabus drafted for your level and the minutes you actually have, ordered so nothing depends on something you haven’t learnt yet. One honest list each morning; miss a day and it becomes backlog rather than a broken schedule.
