Real World Examples?

Hello everyone, is there a chance to get real world examples of the curriculum as you go?

Currently I am going through the Regular Expression part of the JavaScript curriculum, and as I am going through it i keep thinking when I would use this? (I feel like a kid in math class wondering the same lol). I feel like it would help a lot to see an example of it being used. Maybe there could be another button along with the ask for help, get a hint, run test, and reset code.

Just a thought I had. Sorry if this has been discussed before, and if all of the awesome higher up have talked about this already, awesome!

It hasnt been just Regular Expressions that have made me think about this feature. And I meant a button that would show an example, nothing the learner would have to solve.
