📚 Awesome cheatsheets for popular programming languages, frameworks and development tools. They include everything you should know in one single file.

🤔 Why Awesome-Cheatsheets?

I usually make a cheat sheet when I want to improve my skills in a programming language, a framework or a development tool. I started doing these kinds of things a long time ago on Gist. To better keep track of the history and to let people contribute, I re-organized all of them into this single repository. Most of the content is coming from official documentation and some books I have read.

Feel free to take a look. You might learn new things. They have been designed to provide a quick way to assess your knowledge and to save you time.
