PHP developer

As a front-end developer, I’m constantly trying to learn new skills and technologies and adding to what I already know. Front-end developer job postings, however, vary from posting to posting so the list of different languages, libraries, and technologies that could theoretically fall under the category of front-end developer skills is quite large. Here’s a list (that I’ll continue to update) containing a wide variety of skills and technologies that I think all front-end developers should be working on learning, at least to some extent. I certainly don’t know all of these, nor do I expect anyone else to.
