I wrote an article about web front-end frameworks
It might sound a bit out of the place, but I believe, if you are already familiar with p5.js and willing to extend the practice to do web stuff in general, learning front-end frameworks is definitely helpful (and of course if you are looking for a job ). But most of the tutorials and introductions are technical, so I wrote an article targeting creative coders and/or artists. I included p5.js examples for some of them, and I wrote from the standpoint as an artist. I am still learning front-end development and any suggestions are welcome!
