15. Negative Numbers
Miško explores a JavaScript behavior where using negative zero (-0) can lead to slower performance compared to performing zero minus X (0 - X). This phenomenon arises from how JavaScript handles negative zero as a floating-point number, which can disrupt compiler optimizations when accessing properties or arrays with integers, resulting in performance differences between browsers.

16. Holey Arrays
Miško discusses the concept of "holy arrays" in JavaScript, which are arrays that contain holes or undefined values. Reading values from holy arrays can lead to performance issues due to the need to traverse the prototype chain to resolve undefined values, making optimization challenging for JavaScript engines.

17. Amdahl’s Law
Miško discusses Amdahl's Law, which highlights the importance of optimizing code that has a significant impact on the overall application performance rather than just focusing on small, infrequently executed portions. How modern CPUs and virtual machines work together to create the illusion of running JavaScript is also discussed in this segment.
