helloz.js

require("babel-core/register");
require("babel-polyfill");

(async function testingAsyncAwait() {
    await console.log("For Trump's Sake Print me!");
})();

What am I missing? Same thing works finely on my Linux(not sure what else I've done there ages back), but, it doesn't work on MAC right now.

Why does it say 'Unexpected token' for either async or function keywords?

Does babel support async await?. It's ES 2017 no?

Hey Satvik, for async await you need to have transform-regenerator and syntax-async-functions plugin installed and specified in .babelrc

@bharathitman No. True, I was wrong. had to use- Babel preset es2017 plugin

And then did this-

BOZZMOB-M-T0HZ:rest bozzmob$ babel helloz.js --preset > es2017.js

es2017.js-

"use strict";

function _asyncToGenerator(fn) { return function () { var gen = fn.apply(this, arguments); return new Promise(function (resolve, reject) { function step(key, arg) { try { var info = gen[key](arg); var value = info.value; } catch (error) { reject(error); return; } if (info.done) { resolve(value); } else { return Promise.resolve(value).then(function (value) { return step("next", value); }, function (err) { return step("throw", err); }); } } return step("next"); }); }; }

require("babel-core/register");
require("babel-polyfill");

(() => {
    var ref = _asyncToGenerator(function* () {
        yield console.log("For Trump's Sake Print me!");
    });

    function testingAsyncAwait() {
        return ref.apply(this, arguments);
    }

    return testingAsyncAwait;
})()();
