Question
How do Javascript primitive/object types passed in functions?
By Value By Reference None of the above Both A and B
Solution
Both A and B
In JavaScript, primitive types (Number, String, Boolean, Null, Undefined, and Symbol) are passed by value. This means that when they are passed to a function, a copy of the value is actually passed, and any changes to that value within the function do not affect the original value.
On the other hand, objects (including arrays and functions) are passed by reference. This means that when they are passed to a function, what gets passed is actually a reference to the object in memory. Therefore, if the function changes the object's properties, those changes will be reflected in the original object.
