feat: Concurrency/Multi-Threading

Feature Request

Ionic version:

[x] 5.x

Describe the Feature Request

Tapping into concurrency. One of the great things about native iOS and Android development is the ability to use background threads. In iOS, we use Grand Central Dispatch. It would be wonderful if there was a way to run javascript on these threads, so that UI isnt blocked. Not sure if this is possible, but if so that would be a GAMECHANGER.

Describe Preferred Solution

Say theres a long running operation on ngOnInit() function. if we had a plugin which we could throw that long running operation (a heavy function) on the background thread, and when its complete, run the completion method on the foreground that would be sweet.

Describe Alternatives

Related Code

//Native iOS code
DispatchQueue.global(qos: .userInitiated).async { [weak self] in
  self?.runLongRunningOperation()
  // 2
  DispatchQueue.main.async { [weak self] in
    // 3
    self?.updateUI()
  }
}

Additional Context

Honestly, if the capacitor team could implement this, it would make Ionic one step over React Native and be a huge gamechanger for devs.

Thank you!
