TypeScript 5.5 just released and it has a ton of new features, but there are 4 big ones that really stand out to me. By far the biggest is that now TS will properly filter the type of arrays when you use the filter function. This used to be a huge pain to type before, but is now trivial. In this video I talk all about this new feature as well as the 3 other big new changes to TypeScript.
