async/await throwing JSHint errors

[shelby3]

The JSHint included does not support async/await. This feature is incredibly important for modern asynchronous programming.

Please try to invest some resources to fix this.

Could you provide some sample code that JSHint is failing on?

Totally valid. Running KIDE 10.2.1.

const koa = require('koa')
const fs = require('fs-extra')
const app = new koa()
app.use(async function(ctx) {
    let to = './'
    let from = './there/'
    let someVar = await fs.copy(to, from)
    ctx.body = JSON.stringify(someVar)
})

Komodo barks with the following:

• Line 4: "Expected ')' and instead saw 'function'.

Basically, it sees the async as being a var and not a keyword...and then sees the word "function" and flips its shit, thinking there's supposed to be a comma there, etc. etc.

• Line 9: "Expected an identifier and instead saw ')'. Expected an assignment or function call and instead saw an expression.

This is all related to nodejs 7.something (I can't recall at the moment) adding async/await support natively.

Please reopen.

Reproduced. Thanks for the repro code @damianb.

Looks mostly like it's JSHint's fault by the way, after doing a bit of reading; they've been caught unprepared for the merge and general availability of async/await.

jshint has been problematic for us for a variety of reasons, we may have to revisit our JS linting in the not so distant future.
