Fira Code by Nikita Prokopov

Fira Code is an extension of Fira Mono, adding ligatures for common programming multi-character combinations. This greatly improves the time the human eye spends scanning the code and joining multiple characters into single logical operators.

The ligatures are a font rendering feature, so the underlying code remains ASCII-compatible.
