Practical JavaScript Basics

10 sessions of 4 academic hours - JavaScript on real-world JSON data

Real-world data, real rules

Every example uses the JSON report of one device (doc) and a check rule over it - not toy apps.

Press Run under any example, change the code with Edit, and see the output right away.

Each lecture has practice tasks you run with Node.js. Every task checks itself and prints OK or FAIL.
