What are data types in JavaScript?

Can you explain the different data types in JavaScript?

Sure! JavaScript has several data types, including primitive types like string, number, boolean, null, undefined, and symbol, as well as complex types like objects.

What is the difference between null and undefined?

Null is an intentional absence of any value, while undefined means a variable has been declared but not assigned a value.

Can you give me examples of each data type?

Of course! For example, a string can be 'Hello', a number can be 42, a boolean can be true, null is represented as null, and undefined is just a variable without a value.

What about arrays and functions? Are they considered data types?

Yes! Arrays are a type of object in JavaScript, and functions are also objects. They can hold multiple values and can be invoked, respectively.
