Setup Fira Code font for Visual Studio Code

Install Fira Code via brew:

brew tap homebrew/cask-fonts
brew install --cask font-fira-code

Or you can do the same thing with a .Brewfile.
First edit ~/.Brewfile as:

tap "homebrew/cask-fonts"
cask "font-fira-code"

And install with the .Brewfile by the below brew command:

brew bundle install --global

Also, edit your Visual Studio Code settings.json :

{
    "editor.fontFamily": "Fira Code",
    "editor.fontLigatures": true,
}
