Steps

1. This is not a misspelling of NPM, but an official module
2. > Its operation is as follows:
3. It checks if your package exists in your project (so your node_modules folder)
4. If so, then he executes it
5. If not, then it looks to see if it exists in global to execute it
6. If it doesn't exist anywhere, then it temporarily installs it and runs it
7. New flags like --no-install allow to forbid the installation of the package if it is not present in the dependencies of the project
8. It is therefore possible to use packages temporarily, the whole more easily, it is therefore necessary to use this new tool created and made available by NPM
