Understanding How JavaScript Works: From Interpreted vs. Compiled Languages to the V8 Engine Execution Process

This article explains the fundamental principles behind JavaScript execution, covering the distinction between interpreted and compiled languages, the architecture of JavaScript engines (including V8, SpiderMonkey, and JavaScriptCore), runtime environments, the single‑threaded event loop, call‑stack processing, lexical analysis, parsing, bytecode, JIT compilation, and the role of Web Workers in off‑loading CPU‑intensive tasks.

Front‑End Memory Management, Data Structures, and Performance Optimization
