- The ease with which you can code an appropriate hash object and to write the code that works with the hash object.
- Whether the processing speed improves if you use a hash object, and how important this savings is to your application.
Start simple. If you are new to programming with hash objects, it will take practice to make them a tool you readily reach for when you write your programs. The best approach is to start with simple applications that use hash objects as basic lookup ...
