Variable Templates vs Variables
How do I choose between using a variable template and a regular variable?
The choice between using a variable template and a regular variable depends on your specific use case.
If you need a variable that can work with different types and provide flexibility to the user of your code, a variable template is a good choice. It allows you to create a single variable definition that can be instantiated with different types based on the user's needs.
On the other hand, if you have a variable that always uses a fixed type and doesn't require any templating, a regular variable is sufficient. Regular variables are simpler to define and use when type flexibility is not necessary.
