The Machine Underneath

The mechanisms your code stands on — measured, not described.
 
Every episode takes one universal piece of the machine underneath a web app: the event loop, memory, rendering, the network, the bundler. Not a framework, not a version, nothing you have to install to follow along. If you write code that runs in a browser, it runs on these.
 
Every claim here is measured. When you hear a number, the code that produced it is in the description — so you can disagree with me on your own machine.
