AI solution for JavaScript Quiz on BFE.dev
117. `this` VII

The code below outputs:

BFE
bigfrontend

Explanation:

• We defined two classes A and B. A has a static property dev set to 'BFE' and an instance property dev set to 'bigfrontend'.
• B extends class A and has a method log() which simply logs this.dev.
• B also has a static method log() which logs this.dev.
• When we call B.log(), we are calling the static method of B which logs BFE.
• When we create a new instance of B with new B() and call log() on it with new B().log(), we are calling the instance method of B which logs bigfrontend.
