Ecma International recently approved the 2022 standard of ECMAScript. But there is something new in this edition that hasn't been part of prior editions, and this isn't a new programming feature. 🧵 hacks.mozilla.org/2022/06/th…

Our friends @SpiderMonkeyJS implemented the Error cause proposal in Firefox 91* (github.com/tc39/proposal-err…)
The WebConsole displays this new cause property in error messages (and yes, you can have a chain of Error causes 🙂)
* 91 will be Beta/DevEdition later this week
ALT screenshot of Firefox WebConsole, with a snippet throwing a new Error with a cause property. The resulting error message in the console shows the Error and another line below starting with "Caused by:" and then the error that was passed as the cause

Just-In-Time (JIT) compilers are used in all major JavaScript engines to improve the speed, but how do they work? At Global Scope @nbpname will help us understand the principles of JIT compilation, and so how to optimize our code.

Language specification can be a bit of a mystery. At Global Scope, @codehag introduces the stages of the TC39 process for introducing a new language feature to JavaScript, and some high level concerns around our design process.

Honestly, hiring John Howard for any JS engine swag design is now mandatory. The BaldrMonkey t-shirt is my favorite 🔥 monkeyink.com/ink/blog/archi…
