When I run a Javascript file with Deno ...
// file.js
console.log(42)
... doing deno run file.js, then Deno prints ...
←[33m42←[39m
... to the standard Windows 7 console (cmd.exe). What is this, and how can I disable this?
What are these "←[<number>" things Deno prints to the console?

On Windows 7 code coloring is not supported in the standard cmd.exe, resulting in these strange characters.
Solution
If you add an environment variable NO_COLOR=true Deno will not try to color the output anymore and the weird characters will disappear. If you remove the variable again you may have to restart Windows in order to get back the coloring.

A helpful tool to edit environment variables is RapidEE.
If you want the colors, try out a console emulator like for example cmder.
