Progressive Web Apps: The Service Worker Demystified

Adrienne Gessler JavaScript, Problem Solving 4 Comments

You can’t read any technology trend news for the upcoming year without reading about Progressive Web Applications (PWA). PWA offers the ability to add native-like capabilities to your web application.

Tips for Code Review Success

I’ve had the opportunity to be involved in various group peer code reviewing scenarios and sometimes I find myself wondering – is this worth it?
