I have a background in ECS by using C# Entitas. The library itself has a very nice feature which lets me able to query the entity with a specific value in the component.

For example, query an entity with the player component which has an id equal to 1.

However today I need to working on JS Ecsy ECS framework, And there is no way I could query the specific entity by providing a value I want.

What I could do is just iterate through all entities with a player component and filter out all player which isn't equal to 1.

So I want to have about how to deal with this kind of query.

  The library itself has a very nice feature (EntityIndex) which lets me able to query the entity with a specific value in the component.

However when it's come to others ECS frameworks none of them have this EntityIndex feature.

So I want to have more ideas for patterns to deal with this problem, For example,

Want to query an entity with the player component which has an id equal to 1.

I know we can manually index those data using Dictionary and store it in some central component or a system.

But not sure if it's the general thing to do or it's my design flaw lead to this situation...
