javascript - Unexpected identifier when using await -

i'm trying use async/await function requires loop synchronous.

this function:

async channellist(resolve, reject) {     let query = ['channellist'].join(' ');      this.query.exec(query)     .then(response => {         let channelsraw = response[0].split('|');         let channels = [];          channelsraw.foreach(data => {             let dataparsed = responseparser.parseline(data);              let method = new channelinfomethod(this.query);             let channel = await method.run(dataparsed.cid);              channels.push(channel);         });          resolve(channels);     })     .catch(error => reject(error)); } 

when try run it, error:

let channel = await method.run(dataparsed.cid);                     ^^^^^^ syntaxerror: unexpected identifier 

what cause of it?
thanks!

your async defined on channellist , not on arrow function await contained. move async arrow function:

channelsraw.foreach(async (data) => {     let dataparsed = responseparser.parseline(data);      let method = new channelinfomethod(this.query);     let channel = await method.run(dataparsed.cid);      channels.push(channel); }); 

also, since you're using async anyways, can async entire promise chain have there.
