102. Arrow Function II

The code will output:

undefined
"BFE"
undefined

The first getName1() function returns undefined because the this keyword within the function refers to the inner function's scope rather than the class's scope. The second getName2() function correctly returns the name property of the class because it uses an arrow function, which preserves the this keyword to refer to the class's scope. The third getName3() function also returns undefined because it uses a regular function declaration, which creates a new this binding within the function.
