Massively useful! I also recently learned you can right click a line of code in the chrome debugger to add a logpoint - i.e. "log the value of this expression when you reach this point in the code" - so I don't have to manually add console.log statements. Basically the reverse of discovering the debugger statement!
Add a conditional breakpoint with the condition: `value = "someOverrideValue", false` to make the breakpoint change the value when it is reached without actually stopping execution. Great for when you need state changed but the app is always trying to override it. Here's a video from a talk I gave five years ago that demonstrates that: https://youtu.be/uixXOTCNbhs?t=1182
