javascript - unexpected identifier when using awaitasync in nodejs - Stack Overflow

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

You 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
