“That’s why every team needs to consider all the benefits of the statically typed language adoption, decide whether they outgrow the cost and think through why they need a new language.”
A lot of errors may be caught in an early phase of development and be fixed immediately, rather than lurking in the code to be discovered much later.
Refactoring becomes more straightforward with the statically typed language. Developers gain more confidence thanks to the compiler or type-checker, notifying them about the type errors.
Types serve as excellent documentation. It’s easier for new developers to dive into some fragments of the codebase and start working with them without any broader knowledge about the codebase.
Safety that comes with static typing can be a huge productivity boost.
