Been using Chrome on my Windows 10 laptop for a few weeks without any issues whatsoever. Hell I've just jinxed my laptop now

I guess the good news is that no one else is seeing the same issue. The bad news is I still don't know what's causing it. If I ever find out I'll be sure to mention it.

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?
|
|
|
|
|
By definition undefined should be unequal to undefined.
Is it?

Nope, `undefined` is not the answer.
Since `undefined == undefined` returns true in console.
|
|
|
|
|
Ok, I googled it. It's NaN!
Cheers!

Your are very near, but this is not the exact answer

That's bullshit! I've tried it out and surely foo!=foo is true if foo is NaN.

Yup, you are right but here foo is actually NaN, but the question is `What is type of foo`
So, the real answer is `number`
Since, typeof NaN returns "number"
Cheers!

Isn't it amazing, how NaN is a number, how a number is a word and how a word is a string.

yup, the NaN stuff is amazing, but not sure about 'how a number is a word and how a word is a string'

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.

Do you have any reference documentations for it?
I want to learn about it more in-depth. Thanks!
|

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.

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

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

No, undefined compared with anything (anything includes also again undefined) is "an error" and therefore neither equal nor unequal... it is simply again undefined.

It's 2015, IEEE 754 is from 1985, how does this still surprise people after 30 years?

spoiler alert -- answer is below
Opened Chrome Dev console and ran the following.
var x = 'garbage' / 10;
x
NaN
x != x
true
x !== x
true
typeof(x)
"number"

|
|
|
Awesome

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