Meme Monday

Too real...

Don't you just lche it?

You are right! BUUUUT!!!

Then stuff like this happen:
ZeroToHeroGuy79: “Wait a minute cowboy! You didn't do type verification on this one, better try this one:”

if (typeof x == "number"){
   return  x % 2 !== 0
} else {
    throw TypeError(`Value on x is not a number, is: ${typeof x}`)
}

But then someone will tell you:

Brogrammer1024: hol'up brother! typeof is not that reliable, and you can not trust the user, NaN values (Not a number) are considered numbers with typeof and that method will always return true.

DarkDenoBunVader4: “Yeah, the same will happen with Infinity and -Infinity”

Better try this one:

if (typeof x == "number" && !isNaN(x) && isFinite(x)){
   return  x % 2 !== 0
} else {
    throw TypeError(`Value on x is not a valid number`)
}

And it can go on on forever.

x % 2 !== 0 can be wrong. Sometimes, x is not an integer, due to JavaScript's floating point bug.

console.log(NaN % 2 !== 0); // => true
console.log('abc' % 2 !== 0); // => true

Those don't work either. :D

Ah, the meme that is actually only funny to people who know what it means... I could show my mom some of these and she would laugh. I'd be the only one laughing at this one XD
