What are the implications of using global variables?

Using global variables can lead to conflicts and bugs, especially in larger applications, as they can be modified from anywhere in the code.

How can I avoid polluting the global scope?

You can avoid polluting the global scope by using local variables within functions, or by using modules to encapsulate your code.

Can you give an example of a global variable?

Certainly! For example, if you declare var myGlobalVar = 10; outside of any function, myGlobalVar is accessible globally.
