Speed up code your HTML using Emmet in VSCode

#html #emmet #vscode #react

Introduction

On Dec 29, 2020, I had a little reunion with my college friends and my former professor in a zoom meeting. My former professor is Dicky Arinal, and he is working for Disney+ now. The reunion reminded me of when Pak Dicky(We called him using Pak in Indonesia) showed off one of his magics using Emmet, and it made me amazed. However, at that time we were still using Visual Studio because he taught ASP.NET, and we needed to install Web Essentials for using Zen Coding, which is the former name of Emmet.

What is Emmet?

"Emmet is a web-developer’s toolkit that can greatly improve your HTML & CSS workflow:"(https://docs.emmet.io/)

Type "!" + press the "tab" and boom!
