Since the thread about debuggers (here) was closed, I’m adding my answer to it here -
I rely heavily on debuggers and the lack of a proper debugger for Julia and Juno is one of the main reasons I don’t switch to Julia.
I use breakpoints, most of all, as a way of finding my own mistakes - I can write a very readable code in Julia, but even in the most readable code it is easy to miss a displaced minus sign, an edge case not handled in some inner function etc. When working with a large code divided to many sections, breakpoints can save hours looking for the problem, and an uncountable amount of frustration!
Same goes for when using someone else’s code, especially when this code is meant to create abstraction of the methods I eventually plan to use - in general I’m not even trying to understand this code (otherwise, it wouldn’t be abstraction), but when something is not working as I expect, I need all the help I can get understanding it.
