async/await didn't hit javascript until 2017. in 2015 you picked between function foo(cb) {
cb(42, null)
} or function foo() {
return new Promise((resolve, reject) =>{ resolve(42) })
} the second allowed for .then and .catch foo.then((value) => console.log(value)).catch((error) => // handler error) which isn't much better but did get us chaining foo().then((v) => bar(v)).then((v) => baz(v)).catch() |
