GIF
/jīf/
Pronounced just like "life" with a "J". GIF is an image format used exclusively for short animated videos without sound created by 13 year olds on Reddit.
PHP
/phhhhp/
Pronounced about the same as being punched in the abdomen. You can experiment by approaching one of your coworkers and asking them if they would punch you in the abdomen. PHP is a popular programming language for building interactive content on the internet featuring cat videos, SQL injection vulnerabilities, and personal resumes.
JS
/jiz/
This pronounciation should just roll off the tongue. JS files are the backbone of the modern internet. Assuming your backbone is found on the outside of your body, totally exposed to the outside world and all the dangers that implies. JS is usually attributed to the creation of new developers around the world.
