What is scope chaining in programming languages?
Scope chaining refers to the way variables are resolved in nested functions or blocks. It determines how the interpreter looks up variable names.
Can you give me an example of scope chaining in JavaScript?
Sure! In JavaScript, if you have a variable defined in an outer function, inner functions can access it due to scope chaining.
How does scope chaining differ in Python?
In Python, scope chaining works similarly, but it also includes the concept of LEGB (Local, Enclosing, Global, Built-in) to resolve names.
Are there any languages where scope chaining works differently?
Yes, some languages like C++ have different rules for variable resolution, especially with respect to classes and namespaces.
