In TypeScript, it’s often useful to define interfaces or complex (structured) types whose properties (or keys) may only be values of a previously defined enum type. Here’s a good example: an object declaring a set of buttons for a modal dialog. Instead of this… type DialogButtons = {

Universal getter for plain JS objects.
Many times in JavaScript we have to reach deep into objects to access fields that could possibly not be there at all; for example let’s assume I have a JS object called options into which I’ve just read an entire JSON configuration file. Trying to access a field

Recently, I had to make a mock-up of a filtering function (something I need for a project I work on) so I can show-case it around. And since this mock-up seems to impress some people, I decided to share this function with everybody so others may enjoy the
Read moreJS classes for the masses.
Following on an older post of mine, I decided to write a new article about an(other) implementation of OOP Classes in JavaScript. This is something that brings a lot of value from very few lines of code and I want to share it with everyone and see how

Words seem to fail to describe just how awesome LPeg is. Designed as a Lua implementation of the PEG concept, it is a true programming gem! Please, if you dont’t know what it is, take some time to familiarize yourself with it! It’s not the easiest thing to

I know I have been “missing in action” lately but I am working furiously, and I seem to have too little time for my blog (very sad face). But, just for a breath of fresh air, I thought I’d share something with the world. Entering lua2c.lua Lately I
