Yes! Especially since NaN is short for "Not a Number"! X| My whole life is a lie!

Clarified, but how is a number a word (the size of register) and how is a word actually a string (the data type)? :laugh: Plus, short form of your life is a lie (removing the F). :cool:

Sure, read about Word in computer architecture[^] and the string data type[^]. One thing you should know is that there is no actual string type, it is just an array of characters. :-) Good luck for more in-depths.

Thanks for it. Have a nice day ahead! :)

Recently had been debugging using the browser console, when I found this answer. Can you guess the type of foo here? Is it a string, function or else?
Any after overloading operators...

By definition undefined should be unequal to undefined. Is it? Cheers!

Great that you already know the NaN is a number. Now, if you have ever programmed in low-level, you would know that a word is a size given to a data, 1 byte, 2 byte etc. So the size of the register in CPU is a word; pre-defined size, doesn't matter 8-bit 16-bit or what. The size is number, thus, a number is word. :-) Now a word in our language, for example, "Hello", cannot be represented as a word in computer which needs some other type, which is string (array of characters), thus a word is a string. From here comes the metaphor, In programming, a number is a word and a word is a string. :cool:

Great explanation of how semantics and jargon are sometimes or often at odds with meaning.

spoiler alert -- answer is below Opened Chrome Dev console and ran the following.
var x = 'garbage' / 10;
x
NaNx != x // with coercion
truex !== x // even without coercion
truetypeof(x)

How about
int?private static System.Random randy = new System.Random() ;
int foo { get { return ( randy.Next() ) ; } }:-D
