JavaScript the Grumpy Parts
summary
JavaScript is described as a language cloned with its original bugs after Brendan Eich wrote it in ten days and 40 early users froze fixes; the talk demonstrates that hoisting is actually a two-phase compiler behavior, shows concrete var/let/const examples that produce auto-created globals and reference errors, compares bind vs arrow this with setTimeout and call, warns that Babel can turn const into var, and demos event-loop yield tactics like process.nextTick and using Promise.all for parallel async work.
