OzCode VS Prepack

Https://oz-code.com/ has a vs plug in that lets you extract an object. So you can debug to the point you'd like, then right click and get some code to new the current object up. It works OK. If you have private setters or something like that you are out of luck. Source: almost 2 years ago

I have previously used OzCode to do this (and a lot more); however there seems to be some confusion as to what is happening with that product due to a takeover by DataDog that occurred back in November 2021. It's possible to download the 30 day trial, but it doesn't seem possible to actually buy a license at the moment. Source: about 2 years ago

If I understand it correctly, it exchanges execution speed (by not using JIT) for faster starts. Instead, they could pick up the old FB project https://prepack.io/ to optimize both start AND execution speed. It would be very interesting to see it together with node's snapshots: https://blog.logrocket.com/snapshot-flags-node-js-v18-8/, which reduces the start significantly. - Source: Hacker News / 3 months ago

For those uninitiated, Prepack was a neat JavaScript code optimizer. It eliminated computations that could be done at compile time. https://prepack.io/ The project has been dead for quite a while, but it has valid use cases to this day. Source: about 1 year ago

Surely this is the job for something like https://prepack.io/. Source: over 1 year ago

Some real examples in JavaScript can be seen on Prepack[2]. Consequently it is natural to wonder whether we can AOT compile components of client side frameworks, to achieve a reduction in the final bundle size, but also to increase application execution speed. Source: over 2 years ago
