| Short, efficient code | Sometimes hard to understand for external people |
What are the advantages of declarative language?
Enter declarative programming
- It minimizes mutability. Immutable objects are generally much easier to work with.
- It reduces state side-effects. Imagine you’re debugging an unknown view controller, perhaps written by a team member.
- It leads to more understandable code.
- It is just more scalable.

Declarative languages allows for greater extensibility, agility and productivity. Think how quickly you can create a table, input some data and then get the data back in some form or another in SQL and then imagine the time and effort it’d require if you were to implement these in C#.
