Example: what is deffrent between apt and apt-get

DIFFERENCES TO APT-GET(8)
   The apt command is meant to be pleasant for end users and does not need
   to be backward compatible like apt-get(8). Therefore some options are
   different:

   ·   The option DPkg::Progress-Fancy is enabled.
   ·   The option APT::Color is enabled.
   ·   A new list command is available similar to dpkg --list.
   ·   The option upgrade has --with-new-pkgs enabled by default.
