Created a demo app with next.js - day 1 with react.js

Today I created a basic react web app with next.js. I am very excited to learn react.js. I created a blog web app where the blogs are displayed from the files I saved in my project. I followed the steps from the document - https://nextjs.org/ where they have documented everything very nicely so it was easy for me to understand and create.

It was bit easy for me to understand because I come from the IT background. but I am still confused about one point from what I have learned today. If anyone can help me with that, my query is,

1. I am still confused about how getStaticPath works? - I will learn more about it tomorrow.
