Which scoping is more common in programming languages?
Lexical scoping is more common in programming languages; languages like C, Java, and Python use lexical scoping.
Scope determination method in dynamic scoping
In dynamic scoping, the scope is determined at runtime, depending on the order of function calls and the current execution path.
Scope determination method in lexical scoping
In lexical scoping, the scope is determined at compile-time, based on the structure of the written code.
Main difference between lexical and dynamic scoping
Lexical scoping resolves the bindings of variables to their values based on the lexical context, whereas dynamic scoping does so based on the call stack and the runtime context.
What are closures related to lexical scoping?
Closures are a feature that arises from lexical scoping, where a function remembers its lexical scope even when the function is executed outside that scope.
Impact on debugging in lexical scoping vs dynamic scoping
Debugging is generally easier with lexical scoping as the scopes of variables are statically determined, whereas in dynamic scoping, the changing context can make it harder to predict variable values.
