Wolfram Language (Mathematica) Tutorial for Programers

This is a Wolfram Language tutorial for programers. This tutorial is designed especially if you are already familiar with a programing language, such as Python, JavaScript, Lisp .

This tutorial focus on showing you how WolframLang works. You'll be able to code WolframLang in a hour, but most importantly, it make you understand the principle of WolframLang and its symbolic pattern matching that's the heart of WolframLang.

• In Wolfram Notebook, every expression is auto printed after evaluation, unless it ends in Semicolon.
• In WolframScript, either use Print explicitly, or use command line option -print or -print all.

Print[ "something" ]

Print[ x^2 ]
