Summary

That's it for the first chapter. In this chapter, you've already learned a lot about the Salesforce1 Platform and basic Apex concepts. What you should remember from this chapter is that Apex is the proprietary Java-like language of the Salesforce1 Platform. It is strongly typed, case insensitive, and uses single quotes. All statements must end with a semicolon in order to compile. Apex is different from other languages in that it is metadata aware and requires unit testing to be distributed and used in Production environments. Finally, we're sure you won't forget that the Force.com IDE is the preferred tool to develop Apex code and that everything about Apex is documented in Force.com Apex Code Developer's Guide on the Web.

In the next chapter, we'll discuss the limits of Apex and the Salesforce1 Platform. You'll learn about the best practices to avoid them and start working on some code.
