Static types in JavaScript: what, how and why
summary
Shows concrete examples of how JSDoc annotations stop real bugs, with a live use of Google Closure Compiler warnings and WebStorm's refactor- and completion-driven checks. Demonstrates generating and using TypeScript declaration stubs (DefinitelyTyped) to get accurate completions in plain JavaScript, explains typedef/enum/interface tags, and shows when adding types pays off versus when to leave code unannotated. Practical demos and actual error messages appear rather than theory.
