In type-driven development, types are tools for constructing programs. We treat the type as the plan for a program, and use the compiler and type checker as our assistant, guiding us to a complete program that satisfies the type. The more expressive the type is that we give up front, the more confidence we can have that the resulting program will be correct. In Idris, types are first-class constructs in the language. This means types can be passed as arguments to functions, and returned from functions just like any other value, such as numbers, strings, or lists. This is a small but powerful idea, enabling relationships to be expressed between values; for example, that two lists have the same length. Assumptions to be made explicit and checked by the compiler. For example, if you assume that a list is non-empty, Idris can ensure this assumption always holds before the program is run.
