Classic programming techniques in frontend
summary
The talk shows how decades‑old techniques — specifically bit masks and bitwise operations — can encode component state to map bits to CSS classes and reduce large conditional logic to about five lines or a single lookup; a small npm library and repository implementing and testing this approach are published. It also demonstrates modeling form dependencies as trees and compares breadth‑first versus depth‑first traversal to show how traversal order affects render order and perceived UX, using D3 to visualize a job‑skills tree.
