Conclusion

Questions

  • What have we learned?

We have come a long way since console.log('hello, world') in the first lesson. Callbacks and promises, JSON and web servers, packaging, unit tests, and visualization: every modern language can do them, but JavaScript is an increasingly popular choice. Yes, it has its flaws, but if we avoid some of its legacy features, it’s both usable and powerful.

Our journey doesn’t stop here, though. The appendices explore some next steps, such as logging what our server does and using a relational database instead of a text file as a data store. Beyond that, you could look at more advanced techniques in JavaScript Have2018, explore the full power of the D3 library for interactive visualization Meek2017, dive into data wrangling Davi2018, or start over completely the way JavaScript programmers do every eight months and rewrite everything with Web Components. Whatever you do, we hope that this tutorial has helped you get started.
