This is my ultimate vault where I store my cheatsheets and helper online tools or references that make my life easier. I will update it as soon as I find a new one. Let’s get started!

Unix Shell

• http://explainshell.com/ will dissect any shell command you type in and display help text for each piece.
• http://tldr.sh/ pulls out very short descriptive manuals for shell commands.
• http://www.shellcheck.net will check shell scripts for common errors.

CSS

• https://www.joshwcomeau.com/css/interactive-guide-to-flexbox/ explains almost every Flexbox property nicely and breifly.

Javascript

• https://javascript.info/ is an amazing tutorial website, and at the same time is an entire book of Javascript learning content written in a very on-point and easy-to-follow language, it serves as an alternative to the MDN documentation to me.
