更长的方式解释程序

Question

有人可以解释这个更长的路吗？我真的不了解代码的一部分，它是如何工作的。有人可以写得很像：    如果thing =“x”    如果事情= ...

thing = "x" if thing.lower() == "o" else "o"

相当于

var localMediaContainer = document.getElementById('local-video');

var videoElement;

const localParticipant = room.localParticipant; 

room.localParticipant.tracks.forEach(track => {       
    videoElement = track.attach();
    localMediaContainer.appendChild(videoElement);
});
console.log('Connected to the Room as LocalParticipant: ', localParticipant.identity);
