run JS in background of mobile

[arashi-dev]

My app is currently written with v1 for desktop only. and I am planning to migrate to v2.
In my app, there are some logics (mostly HTTP requests) that run in the background using Javascript.
Is it also possible to run JS code in the background of mobiles? if yes, are there any limitations?

I want to decide, whether to keep the logics in JS or rewrite them into rust code
