| ||2 minutes, 10 seconds||Expressions, Types, and Functions - slide 12 : 46|
The notion of type is used to make programs more readable, make them run more efficient, and
to detect certain errors before they cause errors in the calculation.
- Explicitly typed variables, parameters and function
serve as important documentation, which enhances the program understanding.
- Knowledge of the properties of data makes it possible to generate more efficient code
- Explicit information about types in a program is a kind of redundancy against which it is
possible to check expressions and values
- Programmers usually wish to identify type errors as early as possible in the development process
