JavaScript Kicks - JSK Weekly - March 10, 2021

As developers, we're often working with data and data sets in projects for all sorts of reasons, but it's not often we're the subject of data sets! Tom Winter talks us through how they "Sent 304,654 Coding Tests to Developers from 156 Countries" and what they learned.

Something else we don't often look at? The Dark Side of Javascript. Fernando Doglio takes "A Look at 3 Features You Never Want to Use" on Bits and Pieces.
