24. Equality & Sameness

The code output by console.log is:

true
false
false
true
true
true
true
true
false
false
true
true
true
true
true

Explanation:

1. 0 == '0' --> true (loose equality - converts string to number)
2. 0 === '0' --> false (strict equality - different types)
3. Object.is(0, '0') --> false (strict equality - different types)
4. 0 == 0 --> true (loose equality)
5. 0 === 0 --> true (strict equality)
6. Object.is(0, 0) --> true (strict equality)
7. 0 == -0 --> true (loose equality - treats 0 and -0 as equal)
8. 0 === -0 --> true (strict equality - treats 0 and -0 as different)
9. Object.is(0, -0) --> false (strict equality - treats 0 and -0 as different)
10. NaN == NaN --> false (loose equality - NaN is never equal to anything, including itself)
11. NaN === NaN --> false (strict equality - same reason as above)
12. Object.is(NaN, NaN) --> true (checks if both arguments are NaN)
13. 0 == false --> true (loose equality - 0 is falsy)
14. 0 === false --> false (strict equality - different types)
15. Object.is(0, false) --> false (strict equality - different types)
