What are some examples of global scope in programming?

Global scope refers to variables or functions that are accessible from anywhere in the code. For example, in JavaScript, if you declare a variable outside of any function, it has global scope.

Can you give me a specific code example?

Sure! Here's a simple example in JavaScript:

let globalVar = 'I am global!';

function showGlobal() {
    console.log(globalVar);
}

showGlobal(); // This will log 'I am global!'

What are the potential issues with using global scope?

Using global scope can lead to naming conflicts and make debugging difficult, as any part of the code can modify the global variable.

How can I avoid global scope issues?

You can avoid global scope issues by using local variables within functions, or by encapsulating your code in modules or classes.
