WordPress sanitize_title() in JavaScript

As with many problems in programming, this turned out to be more complex than I originally thought it would be. I discovered there were a number of edge-cases that I […]
WordPress Transients

Unfortunately, in this case it isn’t about making the programmers life easier but rather about making the web server’s life easier (and the people who maintain and pay for the web server).
