Looking for a better way to learn the basics of JavaScript in depth? Look no further! The main component of all programs is the arrangement of their variables and functions in different nested scopes. Yet most developers haven't thought deeply about how and why these decisions are made and their impact on code maintenance. The worldwide best-selling "You Don't Know JS" book series is back for its 2nd edition: "You Don't Know" JS Yet." All 6 books are brand new, remastered to cover all aspects of JS for 2020 and beyond Written "Scope & Closures" examines all aspects of lexical coverage, then develops these principles to take advantage of closure power, and finally delves into the module model for better program structure.
