I don't think I've seen a video series or read a book that explains JS/programming concepts as well as you do. I'm a junior developer and you're always my initial source fails to explain something I'm trying to get a deeper understanding of :)

Keep up the good work!

First of all thank you for your interest in uploading these important and useful tutorials.
As per my understanding the following two lines are not mandatory:

1. TechJob.prototype.constructor = TechJob;
2. Job.call(this)

For prototypical inheritance we can also do the following:

TechJob.prototype = Object.create(Job.prototype)
or
TechJob.prototype.__proto__ = Job.prototype
