An example of an AI chatbot conversation about data types in JavaScript.
What are the different data types in JavaScript?
JavaScript has several data types, including undefined, null, boolean, number, string, object, and symbol.
Can you explain the difference between null and undefined?
Sure! 'undefined' means a variable has been declared but not assigned a value, while 'null' is an assignment value that represents no value.
What about objects? How are they different from arrays?
Objects are collections of key-value pairs, while arrays are ordered lists of values. Arrays are a special type of object.
Are there any other data types I should know about?
Yes, there's also the 'symbol' type, which is used to create unique identifiers for object properties.
