I'm getting unexpected identifier when i use async or await in nodejs. I'm on node version 8.5.0. Completely blocked on this. Is there anyway to fix this?
async function methodA(options) {
rp(options)
.then(function (body) {
serviceClusterData = JSON.parse(body);
console.log("Step 2");
console.log("Getting cluster details from zookeeper");
})
.catch(function (err) {
console.log("Get failed!");
});
}
await methodA(options);
console.log("Step 3!");
Tried this after first answer :
var serviceClusterData = "";
console.log("Step 1!");
////////////////////
async function methodA(options) {
await rp(options)
.then(function (body) {
serviceClusterData = JSON.parse(body);
console.log("Step 2");
console.log("Getting cluster details from zookeeper");
})
.catch(function (err) {
console.log("Get failed!");
});
}
methodA(options);
console.log("whoops Step 3!");
Still gets out of order :( Step 1 Step 3 Step 2

Reset to default 5You can't use await outside of an async function.
async function methodA(options) {
await rp(options)
.then(function (body) {
serviceClusterData = JSON.parse(body);
console.log("Step 2");
console.log("Getting cluster details from zookeeper");
})
.catch(function (err) {
console.log("Get failed!");
});
}
methodA(options);
console.log("Step 3!");
'use strict'
function methodA(options) {
return new Promise(resolve => {
setTimeout(() => {
console.log(1)
resolve(true);
}, 2000);
})
}
//Sync Declartion
async function test() {
//Await declaration
await methodA({});
console.log(2);
}
test();
It seems there's is some syntax error in your code. Above code works in 8.5.0
