Exploring the BTP Service Metadata with JavaScript - Part 3

Explore the BTP Service Metadata project in this final installment of a mini-series, focusing on JavaScript implementation. Dive into Node.js, jq, metadata, and functional programming concepts such as lambda expressions, anonymous functions, reduce, filter, map, and concat. Learn to manipulate data structures using Object.keys and other JavaScript methods. Follow along as the instructor demonstrates practical applications, including categorizing entries from the inventory.json file, creating a groupby helper function, and finding applications with free subscription plans. Discover techniques for generating and deduplicating lists of regions across service plans and resources. Gain insights into the multiple parameters passed with map and filter functions, enhancing your understanding of JavaScript's powerful data manipulation capabilities.
