What are some common pitfalls in vanilla JavaScript?

Some common pitfalls include not understanding variable scope, misuse of 'this', and not handling asynchronous code properly.

Can you explain the 'this' keyword and its common mistakes?

'This' can be tricky; it refers to the context in which a function is called. A common mistake is assuming it always refers to the object where the function is defined.

How can I avoid issues with asynchronous code?

To avoid issues, use Promises or async/await syntax. Always handle errors with try/catch or .catch() methods.

What about variable scope? What should I watch out for?

Be cautious with global variables; they can lead to conflicts. Use 'let' and 'const' to limit scope and avoid hoisting issues.
