If you need to go in depth, [Section 7.2.14](https://262.ecma-international.org/9.0/#sec-abstract-equality-comparison) of the ECMAScript spec will help, but otherwise? Stick to three equals (`===`) unless you have a good reason not to. Reinis Ivanovs [htmx 1.9 Released](https://htmx.org/posts/2023-04-11-htmx-1-9-0-is-released/) — htmx ([homepage](https://htmx.org/)) is an increasingly popular library _outside_ of the JavaScript space as it lets folks use things like WebSockets, SSE, AJAX, and CSS transitions by marking up HTML rather than writing lots of JavaScript. v1.9 adds support for view transitions and generalized inline event handling. [The code examples](https://htmx.org/examples/) are worth a look – htmx makes a lot possible, with rather little tooling or markup needed. htmx team [![\](https://copm.s3.amazonaws.com/de9e7382.jpg)](https://imagekit.io/blog/aws-s3-video-streaming-imagekit-video-api/?utm_source=Cooperpress+&utm_medium=email&utm_campaign=JavaScriptWeekly_Newsletter&utm_term=aws-s3) [Supercharge AWS S3 Video Streaming with ImageKit's Video API](https://imagekit.io/blog/aws-s3-video-streaming-imagekit-video-api/?utm_source=Cooperpress+&utm_medium=email&utm_campaign=JavaScriptWeekly_Newsletter&utm_term=aws-s3) — Get adaptive bitrate streaming, video optimizations, format conversions, and real-time transformations and watermarking by attaching ImageKit with your AWS S3 bucket.

The [finished proposals list](https://github.com/tc39/proposals/blob/main/finished-proposals.md) for 2023 now includes [Array find from last](https://github.com/tc39/proposal-array-find-from-last), [hashbang support](https://github.com/tc39/proposal-hashbang), [Symbols as WeakMap keys](https://github.com/tc39/proposal-symbols-as-weakmap-keys), and [change Array by copy](https://github.com/tc39/proposal-change-array-by-copy).
