Some years ago, I published a post related to apply geometry and in particular trigonometry in client-side web applications with high requeriments of animations and interaction. Today we are going to deepen a bit more in this topic studying a subject a little more advanced in the geometry world: rotation matrices.

Some years ago, I wrote a post about how to perform a full-text search in JavaScript modifying the DOM to highlight the results.

If you are aware of the most used JavaScript frameworks nowadays, surely you have heard about Vue.js. If not, next I’ll describe it for you quickly.
Some days ago, I answered a question on Stack Overflow that asked for emulating a JavaScript Popmotion code using the GreenSock library. The original code animates a geometric plane with a tridimensional effect when it is dragged with the mouse.
Answering that question, the next code resulted, that replicates the same effect using just Vanilla JavaScript
