How to use dictionary and other reference type in the component?

I want to use an array, map other reference types as a field in a component.

Which I think I should use @field.ref.

However, want to know a bit more about its behavior.

Is updating the field like so will mark the component as changed?


@component 
export class MyComponent {
@field.ref declare indexes: {[key: string]: Entity};
}

let myComp = entity.write(MyComponent); myComp["newItem"] = entity2; myComp.indexes = myComp.indexes; // Mark the component as changed?



2. Will I going cause the problem with multi-threading by multiple systems trying to access and modify these ref type fields or referenced Entity?
