Thanks for posting here, very nice work!

Do you know the minimum versions of major browsers (Chrome, Firefox, Edge) needed for the Wasm frontend?

Long-term, do you foresee it being feasible to manipulate the DOM elements from Fortran, so that one could effectively write dynamic websites completely in Fortran? I understand this is not in the scope of the project.

I used [ant-design](https://ant.design/) for the front-end components (we could have used (and can still use) any other library as well).

As per [ant-design’s docs](https://ant.design/docs/react/introduce#Environment-Support), they say it is supported on last two versions of major browsers. I guess we can consider the same for our Wasm front-end.

Sorry, I didn’t mean for the UI library, but for the Webassembly part to build and run LFortran.

Those version are mentioned [here](https://webassembly.org/roadmap/)

Chrome: 96  
Firefox: 90  
Safari: 15.2

I am not exactly sure. Probably it might be best to assume last two versions of major browsers.
