What is the difference between instanceof and typeof?
An example of an AI chatbot conversation about the difference between instanceof and typeof in JavaScript.
Can you explain the difference between instanceof and typeof in JavaScript?
Sure! typeof is an operator that returns a string indicating the type of a variable, while instanceof checks if an object is an instance of a specific class or constructor.
Can you give me examples of both?
Of course! For typeof, if you do typeof 'hello', it returns 'string'. For instanceof, if you have let date = new Date(); date instanceof Date returns true.
Are there any types that typeof can't accurately identify?
Yes, typeof can be misleading for certain types like arrays and null. For example, typeof [] returns 'object'.
So, when should I use each one?
Use typeof for primitive types and instanceof when you need to check the type of an object or its inheritance.
