What are the best practices for scope chaining in programming?

Scope chaining is crucial for managing variable accessibility. Best practices include minimizing global variables, using closures, and keeping functions small.

Can you explain how closures help with scope chaining?

Closures allow a function to access variables from its outer scope even after that scope has finished executing, which helps maintain state.

What are some common mistakes to avoid with scope chaining?

Common mistakes include relying too heavily on global variables, creating overly complex nested functions, and not understanding the 'this' context.

How can I improve my understanding of scope chaining?

Practice by writing small functions and experimenting with different scopes. Online tutorials and coding challenges can also help.
