Browser Deep Internals
How browsers really work — from the multi-process architecture and critical rendering path to V8 internals, memory management, the security model, and a step-by-step guide to building one from scratch.
Before you start
Prerequisites
- JavaScript basics — functions, closures, promises, the DOM API.
- HTML & CSS — how markup and stylesheets compose a page.
- Basic networking — what HTTP, DNS, and TCP/IP do at a high level.
- Any systems language — Rust or C++ examples appear in section 18; reading familiarity is enough.
