Four Statements added in ECMAScript Version 3
In 1999, the then new ECMAScript version ES3 got four additions to its statements 1) do-while 2) switch 3) throw 4) try. Did these do good to our coding? Imagine if try would have never been added.

ECMAScript Specification Growth
My inexact word count of the ECMAScript Specification since version 5.1 (2011) to the latest version 13 (2023) has increased by 319.353 words, which is a 57% increase. How did I count words? Open one of the spec URLs and run in your console $('body').textContent.split(' ').length.

CSS has Math Functions
Beside most common one calc() there are functions like min(), max(), clamp(), round(), sin(), cos() and many more. Which allows to write CSS like this width: min(100%, round(var(--my-value)));.

Accessibility Tool Highlight: Tota11y Bookmarklet
A11y Bookmarklet Tota11y "is a simple tool to visualise the most widespread web accessibility errors in a non overwhelmingly-techy way".
I learned this here.
