Explore streaming algorithms in JavaScript and Node.js through this conference talk from JSConf EU 2013. Dive into the complexities of computing averages, maximums, and medians for data streams, going beyond simple finite state calculations. Discover advanced techniques developed by scientists, including the secretary algorithm, lossy counting, and the greedy algorithm. Learn how these methods can be applied when traditional approaches like sliding windows prove too resource-intensive. Gain insights into the history of the Web, JavaScript fundamentals, and statistical concepts such as averages, standard deviations, medians, and percentiles. Access accompanying slides for a comprehensive understanding of streaming data processing in JavaScript environments.
