Explore the history and implications of modularity in software development through this JSConf EU 2017 conference talk. Delve into the origins, meanings, and misconceptions surrounding modularity as a fundamental principle. Examine the motivations behind writing modular code, its impact on complex systems, and the challenges it presents. Investigate the packaged ecosystem, reusable abstractions, and the concept of microservices. Analyze the advantages and disadvantages of modular approaches, including their effects on code extensibility. Gain insights from historical perspectives, including the work of David Parnas, and consider the future trajectory of modularity in the software industry. Discover practical tools and low-level programming concepts related to modular development, while critically evaluating the balance between modularity and other software design principles.
