Javascript isn't hard
Chris Heilmann discusses the complexities and evolving nature of JavaScript, emphasizing its versatility and widespread use in web development. He encourages developers to find their comfort zone within the abundance of tools and frameworks, highlighting the importance of understanding the language and its practical applications. The talk reassures that while JavaScript can feel overwhelming, it should be approached like a buffet, allowing developers to choose what works best for them.

Javascript isn't hard
- 1. JavaScript isn’t hard… ChrisHeilmann @codepo8, SmashingConf Barcelona Jam Session, October 2016

- 3. There is alot of love for JavaScript on the web… 💚❤💙💛💜
- 4. With good reasons… 😃 Veryflexible language 😃 Runs everywhere 😃 Automatically available in browsers 😃 Multiple, open-source engines available 😃 Huge community 😃 Lightweight development environment (text editor/browser is enough?)
- 5. Lately JavaScript hasa lot of visibility which leads to obsession instead of love… 🔥💵📈💯📢
- 6. Which leads toa lot of pressure and anxiety for us developers… 😫😓😭😱😡
- 7. Tell me ifthis sounds familiar… 🤔 I feel like I’m out of the loop 🤔 By the time I get to play with a new JS feature, people already blog it is “considered harmful” 🤔 Everbody talks about flügelhorn.js but I have no idea what I’d need it for – am I building things nobody else does? 🤔 What are all these NPM modules on my HD? 🤔 Why do I get all these warnings when I build something and how come this is not a problem?

- 9. JavaScript used to beeasy - it was just one language in the web stack. HTML (Structure) CSS (Look and Feel) JavaScript (Behaviour)
- 10. Due to itsflexible nature, we extended its use cases massively…
- 11. JavaScript now is alot more… ✅ Web Development ✅ Task runners ✅ Package management ✅ Module-driven development ✅ Extension of software (browsers, editors) ✅ APIs ✅ Services ✅ Servers ✅ Fat client applications ✅ Compilation target ✅ Embeddable runtime ✅ Argument firestarter
- 12. Enhance HTML progressively Use libraries UseAPIs and services Use node, gulp, grunt, NPM and others to manage your tasks and builds Write code for Node, other systems and services to write apps. Different uses require different skill levels…
- 13. Actively participate in systemsused earlier in the timeline… Participate in extending editors and development environments… Work on meta languages and ideas to bridge the gap between JS and higher level languages. Actively participate in inventing the next version of the language
- 14. You do notneed to do all of that…
- 15. You do notneed to use all of that…
- 16. It’s totally OKto pick and choose what you want and feel comfortable with…
- 17. “JavaScript” is nota language, but a whole world of decisions and use cases by now…
- 18. Find your placein this world, travel to other destinations, but don’t feel bad for not becoming a resident in all of them…
- 19. Make yourself more effective… Understandwhat you use and own it… Ownership and responsibility balancing act
- 20. Build tools andprocess balancing act Use what enables others to work with you… Use what helps you write maintainable code…
- 21. Progressive enhancement balancingact Control the UX with JavaScript and own the failure cases. Rely on the browser to give a “working” experience.
- 22. Supporting the pastbalancing act… Use powerful language additions… Don’t block out older browsers and environments…
- 23. I can’t helpyou with all these decisions. It is up to you and the products you work on what makes sense and what doesn’t…
- 24. However, here’s a fewpointers… 🤓 Learn the language - learn how it works, its strengths and weaknesses. 😉 Use polyfills and libraries when you know what they do. Make sure you can remove them and upgrade them if needed. 😍 ES6 is the current, ratified version of JavaScript. Use it, don’t wait for it. 🤓 Promises are an important part of every new JavaScript API. Good to get your head around them. 😱 Don’t panic! It’s a buffet, not a main course. Pick what doesn’t make you sick.
