📂 Full description
Hashmaps are a very useful data structure in programming languages. In JavaScript, data is stored in key-value pairs, using hashmaps to allow for quick retrieval of data. In this course, software engineer and web evangelist Tiffany Graves covers what hashmaps are and why they are used. Learn how the built-in functions for hashmaps, get() and set(), offer quick data retrieval, which leads to an optimal time complexity. Explore the relatively optimal space complexity of Hashmaps in JavaScript, as well. Plus, dive into a discussion of hashing and the basics of what a hash function is.

The Answer:
Programming languages generally employ a strategy called "short circuit evaluation" where they don't evaluate a particular operand if they don't need to. This is exactly what is happening here.
Since the result is going to be false at the 4th element, there is no point in evaluating the rest of the items.
