    Amazing video as usual, mate! I'd just like to point out a potentially misleading piece of information regarding promises. When we use the 'await' keyword, the execution doesn't actually stop; rather, 'await' is just syntactical sugar. What it does is wrap the following code in a nested promise, which will be called once the async function being 'awaited' completes. That's why the main thread keeps doing its thing. Cheers

    At 1:25:22, the console.log('second') is not already in the call stack, still callback functions are not executed. First the log statement got added to call stack, executed, popped then callback functions were executed. So, does the event loop wait until all statements in the program have executed?🤔 Please help here!
