I have made a few Wordpress sites for customers that required me writing Javascript and PHP code as I learned them for quick features and fixes. In other words, I had to write Javascript and PHP code before I even considered myself a programmer, I basically copy-pasted and edited until it worked. I imagine that accounts for a lot of bad Javascript and PHP code. By the time I wrote any C++ or Python professionally I had a CS degree and a decade of programing experience.
