Web workers allow you to execute javascript on a separate thread to the main thread.

I built a web app to create intervals and log workouts.

It’s called BlockJham. It’s quite a simple game, you basically have to tap to swap blocks of the same size but different colours to create a full line of the same colour.

Transitioning between multi page apps has become very easy with the view transitions api.

One of the 3 Core Web Vitals (CWV), web.dev defines LCP as: ‘The Largest Contentful Paint (LCP) metric reports the render time of the largest image or text block visible within the viewport, relative to when the page first started loading’

Console.time allows you to quickly test how long it takes for a block of javascript to execute.

A closure is basically like a bundle of a function and any referenced variables in its lexical scope.

Value vs reference is an important concept in javascript and can be the source of many bugs if not understood correctly.
