What is the difference between virtualenv and -m venv when creating virtual environments (Python)

Question

Sorry if I joked a bit. I am confused by this what is the difference between two    virtualenv myvenv
and
  -m venv myvenv
The first one works well for me in creating virtual environments, while the other one does not.
I cd into my development directory and use " virtualenv myvenv " and it creates a virtual environment. But if I use " -m venv myvenv ", it just gives errors. Please help me understand.
