Javascript引擎实现 discusses the key components of a Javascript engine including the interpreter, compiler, memory manager, garbage collector, standard library, debugger, and JIT. It describes the theoretical basis of memory management and different garbage collection approaches. It also explains several important Javascript concepts like the prototype chain, scope chain, lexical scope, call objects, closures, and how prototypes enable prototype-based programming.

2. Modules： Interpreter compiler：parse, tree-walker code generator memory manager and garbage collector standard library: debugger JIT

6. Prototype-based:No class Performed via process of clone objects(prototypes) focus on behavior of objects

9. Dynamic scope:
