Ruby is the Best Javascript
summary
Claim: Ruby can be made to look and run exactly like JavaScript by abusing metaprogramming. The talk shows concrete tools — method_missing, instance_eval, define_method — plus send, eval, local_variables, Object.new and Class.new, and contrasts them with Opal and therubyracer. The author builds Ruby code that accepts var declarations, console.log and function syntax, then maps those to Ruby methods; it works surprisingly well (including making NoMethodError impossible) but is fragile, insecure and nearly unreadable.
