1. Global Installation:
This command installs a package globally on your system. This means the package's executable files are placed in a directory that's included in your system's PATH environment variable.
As a result, you can run the package's commands from any directory in your terminal.
For example, npm i -g @angular/cli installs the Angular CLI globally, allowing you to use the ng command anywhere.
2. Pros npm i -g (npm install -g):
Convenient for frequently used tools.
Commands are readily available from any location.
3.Cons npm i -g (npm install -g):
Can lead to version conflicts if different projects require different versions of the same tool.
"Pollutes" your global namespace, making it harder to manage dependencies.
