Not clear on why I would want to set a breakpoint

What does a breakpoint tell me?

Where are the best places for breakpoints?

Alternative resource suggestions welcome!

Breakpoints are a great tool for identifying sections of your code that may be problematic.

While debugging, having breakpoints to segment different functions from one another will save you loads of time identifying where your problem(s) lie.

"A breakpoint is a signal that tells the debugger to temporarily suspend execution of your program at a certain point. When execution is suspended at a breakpoint, your program is said to be in break mode. Entering break mode does not terminate or end the execution of your program. Execution can be resumed at any time."

So it is instead of deleting stuff directly in your code/commenting parts of your code out?

For example, setting breakpoint at res.send(posts); in the node-inspector window, is equal to:

app.get('/blog', function(req, res){ 
    //res.send(posts);
});

Is that correctly understood?

So they are used to do a process of elimination?
