What are some examples of static scope in different programming languages?

What are some examples of static scope in different programming languages?

Static scope, or lexical scope, means that a variable's scope is determined by its location within the source code. For example, in JavaScript, a variable defined inside a function is not accessible outside of it.

Can you give me more examples from other languages?

Sure! In Python, a variable defined inside a function is also not accessible outside. In contrast, in languages like C, the scope of a variable defined within a block is limited to that block.

How does this differ from dynamic scope?

In dynamic scope, a variable's scope is determined at runtime based on the call stack. For instance, in languages like Perl, a variable can be accessed by any function that is called after it is defined, regardless of where it is defined.

Are there any languages that use both static and dynamic scoping?

Yes, some languages like Lisp can use both static and dynamic scoping depending on how the variables are defined. This allows for more flexibility in variable accessibility.
