This is how I learn a new programming language the fastest (I think); I'm not sure if it will work for everyone, but why not give it a shot?
You'll need to know at least one programming language to perform this.
Go to the language documentation page first; most of the syntax will be familiar to you from other programming languages. Examine and read several basic programs, such as an input calculator and other starting programs.
Then try to create a program that is a modified version of a simple beginner project, such as a file reader and writer.
