JS Talk July 2017

A talk I gave in July 2017 about modern JavaScript programming. The first half is a series of slides demonstrating new language features in ES2015 and later standards, and how to use tools like Webpack, Babel and polyfills to make them available. The second half is a live-coding exercise in which I build a simple weather report app with React while explaining VDOM, presentational vs. container components, and other basics of writing vanilla React code.

  • AirBNB Style Guide. A style guide that will enforce the use of many of these new features over old-style JavaScript.

  • ESLint. When configured to use the AirBNB style guide settings, a very good way to incrementally learn these new features as you code.
