In Events, are objects passed by Value or Reference (lightning components) ?

When we pass an object by firing events between components , whether they are passed by value or by reference?

I belive its not based on the event .. pass by value and pass by Reference  is based on the attributes whihc you are passing ..

JavaScript. Primitives, such as String, are passed by value

Objects, such as Array or Map, are passed by reference
