What are some common closure errors in JavaScript?

Common closure errors in JavaScript include issues like variable hoisting, unexpected behavior with asynchronous code, and not properly returning values from inner functions.

Can you explain how variable hoisting affects closures?

Sure! Variable hoisting means that variable declarations are moved to the top of their containing function. This can lead to unexpected results in closures if you're not careful about when and where variables are defined.

What about asynchronous code? How does it relate to closures?

Asynchronous code can create closures that reference variables from the outer scope. If those variables change before the closure is executed, it can lead to unexpected results.

How can I avoid these closure errors?

To avoid closure errors, always declare variables with let or const to limit their scope, and be mindful of the timing of your asynchronous code.
