delay using promise instead of setTimeout [duplicate]

Question

I know the output of the code but can anyone please tell me when setTimeout will be called please...

function delay(time) {
    
    return new Promise(function (resolve) {
        setTimeout(() => {
            resolve();            
        }, time);
    })
}


delay(3000).then(function () {
    console.log("run after 3000 seconds")
})
