Meme Monday!

Today's cover image comes from last week's thread.

DEV is an inclusive space! Humor in poor taste will be downvoted by mods.

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

Nah, I think there are many devs that worked with Angular here, you’re not the only one 😅

HB_the_Pencil • Oct 1

I haven't even used Angular, I just get the concepts 😅

Ezpie • Oct 1

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
