"JavaScript, the Real Bad Parts"
summary
Explains five concrete pitfalls and how to fix them: five ways to set this (method, baseless call, call/apply, new, strict mode changes), prototype as a fallback chain using object.create and an object.create shim for old IE, the loop-closure surprise that alerts 3,3,3 and how IIFEs or ES6 let solve it, and how hoisting moves declarations so function expressions vs declarations behave differently; notes Node’s harmony flag for trying ES6 features now.
