await outside of async function doesn't throw error. But MDN says it should












8














MDN says:




Remember, the await keyword is only valid inside async functions. If you use it outside of an async function's body, you will get a SyntaxError.

Try this code in DevTools console, no errors, just result:



async function a(val) { return val; }
await a(10) // await is not inside async function
10


What's wrong with the code or docs?
