You’re building your React Native app.

Things are going great.

But...something is off.

When you go to a new screen the app is unresponsive for a moment… but then everything works like normal again. It’s not a big deal but it’s a problem.

How do you go about debugging that issue?

That’s what we’ll cover in this module. I’m not going to give you the answer to your issue - there could be an infinite number of reasons for the bug you’re currently running into.

What I will do is tell you about some of the  tools available to you as a React Native developer to track down that issue you’re running into.

Ready? Let’s find those bugs and squash them.

To get started first make sure you download the project from GitHub.

Then check out the debugging-start branch.

git checkout debugging-start
