Core Optimizations
Deep performance techniques for maximum speed.
Why this section exists?
This is the "Engine Room". Here, we focus on making the code run as fast as possible on the browser.
The Core Problem
JavaScript is single-threaded. Heavy calculations or too many updates can block the "Main Thread", making the site feel "heavy".
Engineering Patterns:
- Offloading: Moving heavy work to Web Workers.
- Bundle Control: Analyzing and splitting the code so the user only downloads what they need.
- Resource Hints: Preparing the browser for future actions (Preconnect, Prefetch).
Impact: Drastically reduces the time-to-interactive (TTI) and improves the overall user experience.
