Uma implementação em javascript de uma calculadora de Reverse Polish Notation (Notação Polonesa Invertida) onde o código é: // rpn.js if (process.argv.length <= 2) { console.error('missing expression'); process.exit(1); } const stack = []; const operations = { '+': (a, b) => b + a, '-': (a, b) => b - a, '*': (a, b) => b * a, '/': (a, b) => b / a, }; for (let i = 2; i < process.argv.length; i++) { const arg = process.argv[i]; if (Number(arg)) { stack.push(Number(arg)); continue; } const operation = operations[arg]; if ('function' !== typeof operation) { console.error(`unsupported operation: ${arg}`); process.exit(1); } const res = operation(stack.pop(), stack.pop()); stack.push(res); } console.log(stack[0]); // $ node rpn.js 1 2 + // > 3 // $ node rpn.js 1 2 3 * + // > 7 // $ node rpn.js 3 4 + 5 6 + * // > 77

Your platform comes with responsibility. You won’t feel the consequences of your mistakes, so you need to make yourself feel those consequences. Otherwise you’re running open loop & that never ends well."
