Launched The JavaScript Technical Interview Guide here:

Working hard on the last 25%, truly a labor of love. I've been instructing as a coding bootcamp instructor for the last 4 years and this book is answer to :

Will I get a job after this?
How many projects do I need to complete in order to start interviewing?
How can I test my JavaScript knowledge?
How should I prepare for technical interviews? What will I be asked?

The best way for junior developers to circumvent the issue of not having enough experience/projects and still get employed is to do plenty of coding exercises (including on old and newer ES features) without having done whole projects on them.

Hence a guide with over 400 coding exercises + answers!

I'd like to hear what other people might have to say about this. Thanks
