you dont have to wait ten hours to see if it works, you just hit "refresh" and you see the changes you did instantly. most obvious errors that a strongly typed language protects you from are caught by the vm at runtime. then you rely on testing, both automatic testing and manual testing. in a dynamic language you dont have to decide between float or int. your code gets less verbose and you can concentrate on good naming and making the code easy to understand, instead of choosing the right type. also you can have functions that accept many types, which gives you more flexibility and freedom.
