What are some best practices for using arrays in JavaScript?

Some best practices include using array methods like map, filter, and reduce for cleaner code, avoiding manual loops.

Can you explain why using map and filter is better than for loops?

Using map and filter makes your code more readable and expressive, allowing you to focus on what you want to achieve.

What about performance? Are there any concerns with these methods?

While map and filter are generally efficient, for very large arrays, traditional loops may perform better. Always consider context.

How can I handle arrays with mixed data types?

You can use type checking within your array methods to handle mixed types, ensuring your operations are safe and predictable.
