I thought using `const` meant that the variable can’t be edited. If that’s the case, why can we add key-value pairs and edit them? Wouldn’t we want to use `let` instead?

Answer

Remember, the value of a constant can’t be changed through reassignment or redeclared. However, objects are mutable, and in this case, we are altering the object’s contents, not reassigning the object itself.
