Lua in 1 hour

In the continuation of the previous topic, this is a video about Lua from the same author: https://www.youtube.com/watch?v=S4eNl1rA1Ns.

More about interesting features of the language:

• Tail call elimination

• Coroutines support

• Implementation of weak references that do not affect the garbage collector

Also I forgot to mention examples of Lua usage (except games, of course):

• Nginx web server modules

• CloudFlare

• Tarantool

I also note that there is a project called LuaJIT: http://luajit.org/. Using this product you can get really fast Lua programs. And the code is pretty simple and compact.
