Hi @Salariz,
I don't feel particularly able to answer your question but below are a set of links I have collected over the last few years. I thought it may help if I share. The first link should answer your question and the rest are links to things I wish I had found sooner when I started tinkering inside Espruino.

Is there any update about the new Espruino WiFi? On this page it says there is a new version coming out this year but it has said that for a while and there is not much of the year left. I'd be interested in getting my hands on one.
Also, I notice something of an anomaly. The original WiFi board appears on the front page of espruino.com on the scrolling banner thing at £34.50 with a 'Buy Now' button which doesn't actually take the user anywhere useful. When it is found on Espruino Shop, it shows that it is out of stock and listed at £30.

Has anyone tried to make use of the ESP-IDF secure boot and OTA features with espruino?
I'm hoping someone maybe able to share what they've done and what they've learnt.

In addition to the links provided by JumJum, I have found the following to be exceptionally useful while building custom extensions for Espruino on the ESP32.

Hi Gordon, thank you for taking the time to provide a very helpful answer. I feel more confident about what I'm doing now.

I'm learning to create my own extensions for Espruino. I have read the various guides and documentation and referred to existing libraries which have enabled me to succeed in making a simple extension that does not leak memory.
My success is despite uncertainty around the purpose of
jsUnLock()and when to use it. My understanding so far is:- A locked JsVar will not be collected by the GC
- All
jsvNew[Whatever]()functions return locked variables. - Any JsVar that is not intentionally returned to user code should be
unlocked. - Any JsVar that is returned (or child there of) should remain locked.
Have I misunderstood anything? Is there anything significant I am missing?
- A locked JsVar will not be collected by the GC

I have added a comment on that issue.
I am having a go at finding the cause but I can't promise to get results. I only set up an environment for compiling Espruino yesterday and I don't have much experience with C. I will be happy if I can give something back though.
I'm a full stack (and seemingly now embedded) software engineer working on Industrial IoT/SCADA systems. I've been wondering what will happen when I press enter since I began on a Commodore 64. Sometimes I even guess right.
