jsx-control-statements VS dukpy

It's most likely some syntactic sugar plugin for babel. For example, one of these.

Thanks, this is really useful.

I’ve been using this Babel plug-in found it quite intuitive

https://github.com/AlexGilleran/jsx-control-statements

The project I'm now has been using this package for this: https://www.npmjs.com/package/babel-plugin-jsx-control-statements

I know there are libraries like jsx-control-statements and other solutions.

oh good, maybe we can now use python's javascript interpreter in browsers https://github.com/amol-/dukpy

I was interested to see that this uses the DukPy wrapper around Duktape for the JavaScript interpreter: https://browser.engineering/scripts.html

This made me start digging into whether this was considered a "safe" way of executing untrusted JavaScript in a sandbox.

its not completely clear to me if DukPy currently attempts safe evaluation - it's missing options for setting time or memory limits on executed code for example: https://github.com/amol-/dukpy

There's a QuickJS Python wrapper here which offers those limits: https://github.com/PetterS/quickjs

I'm pretty paranoid though any time it comes to security and dependencies written in C, so I'd love to see a Python wrapper around a JavaScript engine that has safe sandbox execution as a key goal plus an extensive track record to back it up!

I didn't write it, but here you go. Thanks to the fact that you can pass Python arguments to the JavaScript function, it will nicely cast them for you (via JSON) and make them behave per a Javascript object, which can then do some funsies to make it act like a string.
