Apexilicious - The Hidden Flavors of Apex
Were you interviewed at Google for Salesforce? Were you asked to work on your coding skills? Or were you recently introduced to Apex programming language? Then Apexilicious is for you.
There are many unknown and powerful features in the Apex programming language that we are either ignorant about or we don't know how to relish. With Apexilicious you will not only kick start with the fundamentals of Apex programming language but also taste the power packed OOPs concepts while building some of the advanced data structures and algorithms, because apex is not just about triggers, handlers, if-else and for loops.

Apex does support bit manipulation with bitwise operators. Apex is filled with features like these and many others that we often do not consider using, probably because we underestimate apex. With apexilicious we will see how much of a performance improvement and clean code can be achieved by leveraging the simplest of these features from this amazing language.
