assert(typeof b === 'number', 'b is not a number got ' + typeof b)
return a + b
}

Last active May 6, 2024 09:04
// Node style module writ in ES6 syntax:
exports default foo = () => console.log(‘hi’)
// Unfortunately “literally” transpiles to this:
exports.default = function foo() {
return console.log(‘hi’)
}
// Which means this will fail:
var foo = require(‘./foo’)
