TypeScript + async / await + throw

in.ts

async function foo() {
    await sleep(1000);
    console.log(1);
    await sleep(1000);
    console.log(2);
    console.log("throwing now");
    if (1 == 1) {
        throw "oh shitshit";
    }
    await sleep(1000);
    console.log(3);
}

function sleep(ms = 0) {
    return new Promise(r => setTimeout(r, ms));
}

foo().then(() => console.log('done'))
     .catch((e) => console.log("Exception happened:", e));

out.js

var __awaiter = (this && this.__awaiter) || function (thisArg, _arguments, P, generator) {
    return new (P || (P = Promise))(function (resolve, reject) {
        function fulfilled(value) { try { step(generator.next(value)); } catch (e) { reject(e); } }
        function rejected(value) { try { step(generator.throw(value)); } catch (e) { reject(e); } }
        function step(result) { result.done ? resolve(result.value) : new P(function (resolve) { resolve(result.value); }).then(fulfilled, rejected); }
        step((generator = generator.apply(thisArg, _arguments)).next());
    });
};
function foo() {
    return __awaiter(this, void 0, void 0, function* () {
        yield sleep(1000);
        console.log(1);
        yield sleep(1000);
        console.log(2);
        console.log("throwing now");
        if (1 == 1) {
            throw "oh shitshit";
        }

        console.log(3);
    });
}
