Summary

Before moving on to the next chapter, you should have lua installed on your computer and you should feel quite comfortable plugging chunks into the lua interpreter. You should have taken a good look at Lua's structures, particularly if/for/while, and especially tables. You should have tried playing with a few functions from the string and math libraries. Important points from this chapter:

• lua is normally executed by a host program or language.

• lua code is broken up into chunks, which are similar to program blocks or single statements.

• Tables are very important in Lua.

• lua is not designed for building huge programs. Its aim is to be useful in creating small programs or parts of a larger system.
