The Birth of V8
A Closer Look at V8's Magic
While the details surrounding the development of the engine are beyond the scope of this article, things like garbage collection and inline caching are worth exploring. These concepts along with hidden classes are what largely contribute to V8's performance advantage.
It's no wonder the V8 engine has been applied to everything from database engines (MongoDb) to web servers (Node/Express). By understanding how the V8 engine works, developers can better organize code to leverage things like hidden classes and just-in-time compilers that V8 relies on to excel with performance.
