Links, Picks, and Tips:
Alex Liu
  • Tips: Always think about Errors and error handling as part of the design and spec from day one and Understand the abstractions you use, especially when it comes to Errors
  • Picks: VError, bunyan, restify-errors, and Overheard - VS Code debugger is great
Brian Lonsdorf
  • Links: Elm’s debugger and Free Monad graph
  • Tips: Algebraic data structures like Either, Task, and Maybe ensure we handle all errors. The errors are pushed to the caller where it’s easy to see., In node, you can overwrite Obj.prototype.inspect to display a custom string when console.log-ing., and Learn to use debugger; in the browser.
  • Picks: Bodil Stokke Generators and Profunctor Lenses
Kyle Simpson
  • Tips: Chrome CPU Throttling, OSS your code early. Don’t wait until “it’s good enough for others”, because then you’ve waited too long. OSS is about collaboration and improvement, not promotion of already-finished code., and Start with libraries and frameworks as you rapidly develop/evolve/explore a project. But as it matures, try to build time in for refactoring to reduce/remove those pieces. You don’t need them permanently. The best code is the code that’s exactly what’s needed, no more, no less.
  • Picks: About the new ‘createImageBitmap(..)’ API and also ‘requestIdleCallback(..)’, Chris & Getify Make A Game (part 1) tutorial on simple <canvas> game making with me and @chriscoyier, and Cloud Sweeper my first <canvas> casual web game, OSS code released
