NativeScript - What is the difference between viewModel.foo and viewModel.get(“foo”)?
Take the following simplified viewModel:
const observableModule = require("tns-core-modules/data/observable");
function HomeViewModel() {
const viewModel = observableModule.fromObject({
foo: 'Hello World'
});
return viewModel;
}
In NativeScript, it's possible to get a viewModel value in two ways:
viewModel.foo and viewModel.get("foo")
In which case should I use the latter?
javascript mvvm nativescript viewmodel

Both are actually same when creating an Observable using fromObject method.
viewModel.foo will internally be mapped to viewModel.get("foo") / viewModel.set("foo", value) using Object.defineProperty.

So that means, I don't have to useviewModel.set("foo", value)either? I could just useviewModel.foo = value? (I never dared to do so, lol xD)
