TypeScript tuple inference

You can use the tuple() function in tuple.ts to infer tuple types in TypeScript and cut down on the need to repeat yourself. Without tuple(), declaring a constant of a tuple type looks like this:

const daysOfTheWeek: ["sunday", "monday", "tuesday", "wednesday", "thursday", "friday", "saturday"] = 
  ["sunday", "monday", "tuesday", "wednesday", "thursday", "friday", "saturday"];

You can't do this:

const daysOfTheWeek = ["sunday", "monday", "tuesday", "wednesday", "thursday", "friday", "saturday"]; 

Important: At the time of writing (2019-11-11) Immutable.js is effectively abandonware, so I can no longer recommend anyone to follow the advice given here. I'll leave the article here for posterity, since it's still getting some traffic.

Understanding Immutable.Record

Functional programming principles and with it immutable data are changing the way we write frontend applications. If the recent de-facto frontend stack of React and Redux feels like it goes perfectly together with immutable data, that's because it's specifically designed for that.

There's several interesting implementations of immutable data for JavaScript, but here I'll be focusing on Facebook's own Immutable.js, and specifically on one of i

How to recover a git branch you accidentally deleted

UPDATE: A better way! (August 2015)

As pointed out by @johntyree in the comments, using git reflog is easier and more reliable. Thanks for the suggestion!

 $ git reflog
1ed7510 HEAD@{1}: checkout: moving from develop to 1ed7510
3970d09 HEAD@{2}: checkout: moving from b-fix-build to develop
1ed7510 HEAD@{3}: commit: got everything working the way I want
