The Modern JavaScript Bootcamp (2019) - Object References

The video tutorial explores the concept of passing objects in JavaScript functions, using an expense manager application as an example. It explains how objects are referenced in memory, demonstrating that changes to an object within a function affect the original object due to shared memory references. The tutorial also covers creating and manipulating objects, specifically focusing on an 'add expense' function. It concludes with experiments on object assignments, illustrating how assigning new values breaks the reference binding.

In the context of the expense manager application, how do you expect the add expense function to behave?

What happens when we pass an object into a function in terms of memory reference?

How does the behavior of passing objects into functions affect the original object?

What would happen if you assigned a new object to an argument that was passed into a function?

Explain the significance of modifying properties of an object passed as an argument.

What is the difference between manipulating an object's properties and assigning a new value to the argument in a function?

Describe the implications of having multiple variables reference the same object in memory.
