JavaScript - From Birth to Closure
summary
History and mechanics of JavaScript from 1995 to modern engines, with concrete demos: polyfilling Array.push to fix old browsers, explaining why == vs === bites with type coercion, showing an addFive closure example that captures outer state, fixing the loop-onclick bug via a self-invoking function fix, using call/apply for context, implementing a Curry via Function.prototype, demonstrating the module pattern for private members, and recommending tools like JSLint and JSMin for safer, smaller code.
