What are some common errors with scope in programming?

Common scope errors include variable hoisting, closures, and the misuse of 'this' keyword.

Can you explain variable hoisting?

Sure! Variable hoisting is when variable declarations are moved to the top of their containing scope during compilation.

What about closures? How do they cause errors?

Closures can lead to errors when they capture variables from their parent scope, which may not behave as expected.

How can I avoid these scope errors?

To avoid scope errors, always declare variables with 'let' or 'const', and be mindful of the context in which functions are called.
