Using Cardano-wallet js API beginner

Developers Cardano Integration

I have index.js

const { WalletServer } = require('cardano-wallet-js');

// first you need to docker compose to get a access point to the blockchain

// curl the access point

// curl http://localhost:8090/v2/network/information

// your-server-host?

// {port} 8090

let walletServer = WalletServer.init('http://localhost:8090/v2');

let information = await walletServer.getNetworkInformation();

console.log(information);

var start = async function() {

    let information = await walletServer.getNetworkInformation();

    console.log(information);

}

I run the script as node index.js and I get a error it says a Syntax Error wait and I have docker compose up as wallet service. This is straight from cardano developer docs. Feel like I am missing something.

PS E:\JubliantMarket\jubilant-market\Front-end\demo\src\CardanoWallet> node index.js

let information = await walletServer.getNetworkInformation();
^^^^^

Nevermind I am just a idiot have to wrap the code from the documentaiton in a async function


async function asyncCall() {

    let information = await walletServer.getNetworkInformation();

    console.log(information);

}

asyncCall();
