描述
var foo = async () => {
console.log(1);
return (await 1) + 2;
}
foo();
console.log(2);
should transpile to:
var foo = function foo() {
return new Promise(function (resolve) {
console.log(1);
resolve(1);
}).then(function (_resp) {
return _resp + 2;
});
};
foo();
console.log(2);
which should log 1, then 2.
but instead transpiles to:
var foo = function foo() {
return Promise.resolve().then(function () {
console.log(1);
return 1;
}).then(function (_resp) {
return _resp + 2;
});
};
foo();
console.log(2);
This difference means the async function takes an extra tick - which results in logging 2, then 1.
