Why isn't Moddable more popular?

[linfan68]

I have a somewhat unusual background: I used to work on a lot of JS projects (specifically TypeScript) for both servers and front-end development. About two or three years ago, I jumped into an embedded development project where I started with something as simple as lighting up an LED (after burning out a couple of LEDs). Later on, we customized our own operating system based on FreeRTOS, developed a complete set of hardware abstraction layers, iterated through multiple chips with different architectures, and finally produced the product.

Because of this background, from the first day I started working on embedded systems, I have been looking for a suitable solution to develop embedded systems using JS. Every now and then, I search on Google to see if there are any new projects available.

If you search for Javascript + IoT, Javascript + Embedded, Javascript + ESP32, the Moddable project will not appear in the search results! I have tried three or four different JS frameworks for embedded systems, but none of them have reached the maturity level required for use in large-scale projects.

A few months ago, a colleague informed me about this project, and today I have successfully ported core part of my project's code. This has dispelled most of my doubts, and I believe that this is a mature enough framework to support production-level projects.

My question is, why isn't Moddable more popular? It's difficult to find information about it on Google. Here are a few possible reasons come out of my mind:

• License limitations?
• Steep learning curve? Although the Moddable documentation is detailed, the style may be different from modern projects, making it challenging to learn without assistance.
• High-performance embedded devices with large ROM/RAM are not yet popular?

What are your thoughts on this matter?
