Programmers use a lot of symbols, often encoded with several characters. For the human brain, sequences like ->, <= or := are single logical tokens, even if they take two or three characters on the screen. Your eye spends a non-zero amount of energy to scan, parse and join multiple characters into a single logical one. Ideally, all programming languages should be designed with full-fledged Unicode symbols for operators, but that’s not the case yet.
Fira Code is a free monospaced font containing ligatures for common programming multi-character combinations. This is just a font rendering feature: underlying code remains ASCII-compatible. This helps to read and understand code faster. For some frequent sequences like .. or //, ligatures allow us to correct spacing.
Then:
Fira Code is a personal, free-time project with no funding and huge feature request backlog. If you love it, consider supporting its development via GitHub Sponsors or Patreon. Any help counts!
Left: ligatures as rendered in Fira Code. Right: same character sequences without ligatures.
Fira Code comes with a few different character variants, so that everyone can choose what’s best for them. How to enable
In addition to that, Fira Code contains huge variety of Unicode characters well-suited for technical writing, math formulas and terminal UIs.

In case you want to alter FiraCode.glyphs and build OTF/TTF/WOFF files yourself, this is setup I use on macOS:
# install all required build tools
./script/bootstrap
# build the font files
./script/build
# install OTFs to ~/Library/Fonts
./script/install- Author: Nikita Prokopov @nikitonsky
