not support `await`?

'Await' may not be used as an identifier in this context"

hey @tigercosmos , can you please share an example?

[tigercosmos]

here is the example code:

  await new Promise((resolve, reject) => {
      // ...
  });

@tigercosmos I've added a spec to ensure that parsing/generation of async/await works:

const test = require('ava')
const {
  generate,
  first,
  parse
} = require('../../..')

test('async-await: can be parsed and generated', assert => {
  const source = `
    async function foo () {}

    (async () => {
      await foo()
    })
  `
  const tree = parse(source)
  assert.truthy(first(tree, 'AwaitExpression'))
  assert.truthy(first(tree, 'FunctionDeclaration[async=true]'))
  const output = generate(tree)
  assert.truthy(output)
})

Please note, that await must be used within an async function. It cannot be used within the top level scope (at least e.g. in Node 14~).

^^^^^

Uncaught SyntaxError: await is only valid in async function

Does this help?
