What are the fundamental data types in JavaScript, and how do they differ in terms of characteristics and use cases? I'd like to understand the distinctions between primitive data types like numbers, strings, booleans, null, undefined, and symbols, as well as reference data types like objects and arrays.
Can you explain how JavaScript dynamically assigns data types and how type coercion works? Furthermore, I'm interested in learning about the role of type of and instanceof operators in type checking.
Lastly, how can developers effectively use and manipulate these data types in real-world scenarios, such as data validation, mathematical operations, and data storage? Are there any best practices for optimizing data type handling and ensuring code reliability in JavaScript applications?
