Just discovered your channel and it's just awesome, keep up the good work man.

Awesome work dude.
One suggestion
do not use # in the first place while declaring a variable it looks weird.

[evolvingbackwards]

at 2:37 can you please explain the use of docCall(); and how it is working?

[cryptoeraser]

This is a great video. All of your video's are amazing. Thanks for your time and effort. One question, why using the recursive approach here? Why not simply iterate over a list of Queue objects and consume those individually? Thanks.

Why do you use # and not let? for declare vars. And what is the name of this form to declare variables??

[psychomafia]

this is very cool, but there is no actual way to interrogate the status of an actual printer through javascript is there?
