Passing arguments to a function using async/await

Question

I'm trying to pass arguments to a function that uses async/await. I've defined my function like so

// common.js

export const myAsyncFunc = async (t, textA, textB) => {
  await t
    .typeText('#input-1', textA)
    .typeText('#input-2', textB);
};

However, when I try to import this function to another file, like so, I can't pass it t because t is not defined:

// index.js

import { myAsyncFunc } from './common'

myAsyncFunc(t, textA, textB)

Is it possible to just pass in my textA and textB arguments (possibly with currying or another way) with async/await?

EDIT: So this is being run as part of the test cafe library. It looks like t comes from when testcafe chrome client/__tests__/ is run, rather than being imported in the common.js file.

Well, you haven't defined `t`, so it's not defined, which is what I think the error message is actually saying. — Heretic Monkey, Jul 17 '17 at 15:29
@Jonasw Yeah, I've never seen an error which states "is not undefined". I think the error is actually "is not defined", or "is undefined", because it's trying to run functions on `t`, which is undefined (at least from the little code provided). — Heretic Monkey, Jul 17 '17 at 15:33

You are importing/exporting myAsyncFunc, but in your code you are calling myAsyncFunction.

Also, you are chaining

.typeText('#input-1', textA)
.typeText('#input-2', textB);

But I think .typeText returns a promise, right? So you should:

export const myAsyncFunc = async (t, textA, textB) => {
  await t.typeText('#input-1', textA);
  await t.typeText('#input-2', textB);
};

Other than that, the code is working just fine, assuming you defined t somewhere, as pointed out in the comments.
