The "noob" way I'd argue is more readable than using an arrow function like the "pro"

[luigivids]

It's not "noob" and "pro" it's just the first is older and the 2nd uses newer arrow functions

[mariandecker]

bool isEven(int num){
return num % 2 == 0;
}

[LAXMAN_DON-tm]

for me pro is who's code is easly readable and understandable even for beginner

[jecocri]

I'd still use the function as shown in method #1. You could just write:
return num % 2 == 0;
inside of the function though.

[realGeobor]

In C or C++:
bool isEven(int i)
{
return !(i & 0b1);
}

[singularsquids]

They’re doing the exact same thing, just one of them is much easier to read and know what’s going on.

[sachinacharya]

section .text
global isEven

isEven:
test rdi, 1 ; Bitwise AND with 1 (checks if LSB is set)
setz al ; Set AL to 1 if zero (even), 0 otherwise
movzx rax, al ; Zero-extend AL to RAX (return value)
ret

Don't know why ppl saying the noob's version is more readable??? Bruh, the top one gives me a headache just looking at it, not bc it's "confusing" or "harder to understand", but simply bc it is more reading.

The buttom one is quicker to type out, quicker to understand, and is overall just more efficient. The noob's code is like "shakespearean" english, while the PRO is like modern english, quicker & more concise.

Like why is the noob's code telling me this is a function, I can tell from the parameter and arrow of the pro's code that this is a function.

[girijasankardas]

In java u can only write return statement with return number%2==0 no need to write anything else

[curiosity-uf]

I alternate between these depending on my mood and how lazy i am at a moment.

It's not about syntax, He highlights that the noob will check the operation result if true or false and then will decide if he will return true or false while the operation itself returns true or false

[danielbengtsson]

The "pro" way is also noob. You don't need a function to check if something is true or not, at that point you're just bloating your code, and you won't even remember half the functions you've created. Just do this in the function or loop or whatever you need to check if something is even or not:

let isEven = num % 2 === 0;

[sf-petru]

the pro code is the way a noob think the pro writes code

[anonimzwx]

Mod is slow compared with bitwise and

return (num&1)===0 is optimal

[ArianitKnushi]

It is so relaxing that you have a vocal only music and not like the other with instruments

[joaquimrdam]

when a function is extremely small, arrow functions will always be better, and how would it not be readable? the name of the function is isEven with a "num" parameter...

[amir-ww]

Also No need for () around the num in pro one

[sols-it]

Can you tell the music background for this short? I'm in love, great choice.

Noob: Use general words when talking
Pro: Use a lot of skibidi slang when yapping
