On: Ask HN: How do you debug your code?

[greenyoda]

"Don't think of the debugger as a debugger, think of it as a REPL."

That's a great analogy.

"You just happen to be using the REPL with buggy code."

Despite the name "debugger", it's not just for buggy code. A debugger can be a very useful tool for understanding how someone else's code works.
