Before we can improve the performance of some code, we need to be able to monitor its speed and efficiency to record a baseline we can start measuring from.
What is the best type to use for a scenario? To answer this question, we need to carefully consider what we mean by best. We should consider the following factors:
- Functionality: This can be decided by checking whether the type provides the features you need
- Memory size: This can be decided by the number of bytes of memory the type takes up
- Performance: This can be decided by how fast the type is
- Future needs: This depends on the changes in requirements and maintainability
There will be scenarios, such as storing numbers, where multiple types have the same functionality, so we will need to consider the memory and performance to make a choice.
If we need to store millions of numbers, then the best type to use would be the one that requires the least number of bytes of...
