How to set up a Local Host

Hello, first time posting here…

I just started to use p5.js coming from python, and wanted to try something with p5.sound.
but I’m having an issue with preload (), it’s not loading the sound file and web page is stuck on “Loading…”
I’m guessing it’s a local host thing since I don’t know much about and probably made a mistake there, but I don’t know what to do from here.
I’m using Windows 10 and Atom.

I don’t why, but when I tried the Web server for chrome extension again it worked. may be I didn’t use it properly. Thanks for the replay.
