- The prototype property is used when updating and retrieving an object's properties.
- In the method invocation pattern, a function returns what value if there is no explicit return statement? (one word)
- In the constructor invocation pattern, a function returns what value if there is no explicit return statement? (one word)
- In the function invocation pattern, this is bound to which object? (one word)
- The apply function invocation pattern does not allow you to set the value of this. (true/false)
- The use of that is to get around the limitations of the function invocation pattern. (true/false)
- The for in construct in JavaScript is not so useful because it loops over all of the accessible properties of an object. (true/false)
