Error: "resolve not defined"

Hello there! Could anyone please help with this... I've typed out the code exactly as Guil described in the video:

// Code start

const newPromise = new Promise( (resolve, reject), setTimeout(() => { resolve("Your order is ready!"); }, 3000) );

console.log(newPromise);

newPromise.then((val) => console.log(val));

// Code end

However I get an error in return when I run it in the workspace and on vscode:

(resolve, reject), ^

ReferenceError: resolve is not defined

You want the promise to take a arrow function with a resolve and reject. You have to change..

const newPromise = new Promise( (resolve, reject), setTimeout(() => { resolve("Your order is ready!"); }, 3000) );

to

const newPromise = new Promise( (resolve, reject) => setTimeout(() => { resolve("Your order is ready!"); }, 3000) );
