How to learn a new programming language

[lefticus]

I'm often asked this question, so here's some guidelines all in one place:

• Find the official language documentation. It will be up to date.
• Be leery of the top search engine results. They are old and have gamed the system. This isn't true all of the time, but keep your eye open for it.
• Consider asking one of the AI systems for a bespoke example in your new language. The example might not be 100% correct, but it will likely point you in the right direction
• Pick a project you have done in the past and port it to your new programming language (NES Emulator, Game of Life Simulator, Mandelbrot browser)
• Look to Coding puzzle websites like Project Euler and Advent of Code
