CoffeeScript for the Rubyist

on YouTube ↗38m

" summary

CoffeeScript compiles to JavaScript and presents concrete substitutions: shorter jQuery AJAX calls, Ruby‑style lambdas, splats, default args, ranges (note: 1..100 switches implementation at 22), class constructors with @ as instance variable assignment, inheritance, and bound callbacks via the fat arrow to fix this scope. Syntax enforces significant whitespace and relaxed parentheses, emits strict mode, and offers the existential operator (?) to safely call console.log or chain property access without runtime errors.
