An example of an AI chatbot conversation about programming language scopes.
What are the different scopes in programming languages?
In programming, scope refers to the visibility of variables. Common types include global, local, and block scope.
Can you explain global scope with an example?
Sure! In global scope, a variable is accessible from anywhere in the code. For example, if you declare var x = 10; outside any function, x can be accessed in any function.
What about local scope?
Local scope means a variable is only accessible within the function or block where it is defined. For instance, function test() { var y = 5; } makes y inaccessible outside test().
Are there any languages that handle scope differently?
Yes, languages like JavaScript use function scope, while others like Python use block scope. Each language has its own rules.
