Path Literal

Paths are natively presented in nix instead of as strings

Path interpolation

Path can be created from string evaluation

rec {
    user = "john";
    home = /home/${user}/ 
}

INFO

Path interpolation requires at least one slash before any value were interpolated. ${user}/${email} wound be lowered as a division operation while ./${user}/${email} is a path

Path concatenation

./foo/bar + "file.txt"
