What are the best practices for type conversions in JavaScript?

When converting types in JavaScript, it's important to use explicit conversions to avoid unexpected results. For example, use Number() for converting strings to numbers.

Can you give me an example of implicit vs explicit conversion?

Sure! Implicit conversion happens when JavaScript automatically converts types, like adding a number and a string, which results in a string. Explicit conversion is when you manually convert types, like using String(123) to convert a number to a string.

What about converting objects to primitive types?

For objects, you can use the valueOf() or toString() methods to convert them to primitive types. It's crucial to understand how these methods work to avoid errors.

Are there any pitfalls I should be aware of?

Yes, be cautious with type coercion, especially with equality checks. Using == can lead to unexpected results due to implicit conversions. It's safer to use === for strict equality.
