33. `this` II

The code below outputs the following by console.log:

1
1
1
1
1
1

Explanation:

• obj.b() returns 1 because this.a refers to the a property in the obj object.
• (true ? obj.b : a)() also returns 1 because true is evaluated to true and obj.b is passed to the function call instead of the a variable.
• (true, obj.b)() also returns 1 because the comma operator evaluates true and returns obj.b as the final value.
• (3, obj['b'])() returns 1 because the comma operator evaluates 3 and returns obj['b'] as the final value.
• (obj.b)() returns 1 because obj.b is a function and is called to return the value of this.a.
• (obj.c = obj.b)() returns 1 because obj.c is set to the b function of obj, and the function is called to return the value of this.a.
