πŸ“‚ 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.
