What is the scope in programming languages?
Scope in programming languages refers to the visibility and lifetime of variables and functions in your code.
Can you explain the difference between local and global scope?
Local scope means a variable is accessible only within a specific function, while global scope means it's accessible throughout the entire program.
How does scope affect variable hoisting?
Scope affects variable hoisting by determining where variables can be accessed before they are declared, which can lead to undefined behavior.
What are some common scope-related errors in programming?
Common scope-related errors include referencing variables that are out of scope, leading to errors like 'undefined variable'.
