Math4devs.com: List of mathematical symbols with their JavaScript equivalent

I like this a lot. I've been going through HS-level math with Math Academy and I'm always intrigued when I see these symbols in advanced calculations elsewhere online.

I recently learned the syntax for half-open intervals. It's so frustrating that I can't bear to type it out. This is relevant: https://xkcd.com/859/

My son is using Math Academy and it's been excellent. A really good system if anyone is looking for online math course.

I've been at it consistently for a month, it really is good. The only downside is that I'm desperately on the search for other courses with its format to no avail.
