Trie Demo

It says "directed acyclic word graph", which I think is the correct term, but I just found out on Wikipedia that this is indeed a trie. The difference is illustrated quite precisely, but I think it's really the same thing. I didn't use an existing algorithm, but I just made this up myself. I didn't study computer science (and I'm mostly glad I didn't). If you did, let me know if it's any good.

Abandoning hope... and XForms

Sometimes a decision must be made. I have invested many hours in a standard that is quite complex and tedious to maintain, and that was great fun, but enough is enough. Why did I invest in XForms when it took so much effort and time? Because I believe standards are good and good standards come from the W3C and the XML community. Also, I always had somewhat of an inferiority complex in IT development that I tried to compensate by using techniques supposedly invented for common folk, i.e. non-programmers. Both are bad reasons from where I now stand. I took up XForms because I was infected by the enthusiasm of a friend (who was even quicker to abandon it) about 3 years ago. At first I assumed it just used a model from which to infer a form. It turned out it was like a superset of HTML forms with options for displaying and validating data. This was largely taken up by HTML5, as we all know. The Model remains the core of XForms, but the W3C is slow to respond to innovations and the need f

JS Journey into outer space - Day 5

This article was written as part of a knowledge sharing program I created for front-end developers. It builds up to creating reusable abstractions by studying async transducers. Day 5 It's time to add more operators. We already have map , but what if the mapping function returns another "container" value, like an array or observable? 🦉 In RxJS some operators like switchMap , concatMap , or mergeMap will expect a "project" function that returns an observable (or promise or array), but what happens then? First map is applied with the project function and after that the result is "flattened". In other words: when the returned (inner) observables emit, the mapped (outer) observable emits those values instead. Since RxJs streams have a specific async behaviour the flattening process takes concurrency into account: mergeMap will flatten inner observables whenever they complete, regardless of the order, but concatMap will preserve the order of the ou

JS Journey into outer space - Day 2

This article was written as part of a knowledge sharing program I created for front-end developers. It builds up to creating reusable abstractions by studying async transducers. Day 2 That's all good and nice, but wait just one moment! I'm already using RxJS (or Lodash or your framework here) and it already provides composable operator functions! You Ain't Gonna Need It? You would be right of course, and getting invested in yet another new framework for that extra bit of performance might not be worth it. However, do you need separate frameworks if there would be a single one to do all you need? Does it even exist? At first glance transducers-js looks great, but the first thing you might notice is that it hasn't been updated recently and doesn't use TypeScript. And of course we want typed functions. A nice typed functional framework is fp-ts . It's also quite complex, due to its abstract nature (if not its scarce documentation). Let's see if we can fa
