What are some examples of dynamic scope in programming?
Dynamic scope refers to a variable's accessibility based on the call stack at runtime. A common example is in languages like Perl or JavaScript.
Can you give me a specific code example?
Sure! In JavaScript, if you define a variable in a function and call another function that uses it, it can access that variable if it's in the call stack.
How does this differ from static scope?
Static scope, or lexical scope, means a variable's accessibility is determined by its location in the source code, regardless of the call stack.
Are there any languages that use dynamic scoping?
Yes, languages like Perl and some Lisp dialects use dynamic scoping, allowing for more flexible variable access.
