Closing thoughts
Being able to easily link C++ modules with your Node program is a powerful new paradigm. It may be tempting, then, to exuberantly begin writing C++ add-ons for every identifiable segment of your programs. While this might be a productive way to learn, it is not necessarily the best idea in the long run. While it is certainly true that in general, compiled C++ will run more quickly than JavaScript code, remember that V8 is ultimately using another type of compilation on the JavaScript code it is running. JavaScript running within V8 runs very efficiently. As well, we don't want to lose the simplicity of organization and predictable single-threaded runtime of JavaScript when designing complex interactions within a high-concurrency environment. Remember: Node came into being partly as an attempt to save the developer from working with threads and related complexities when performing I/O. As such, try and keep these two rules in mind:
- Is a C++ module actually going to run...
