That's one way to do it
-
That can be done better with a recursive function:
function IsEven(number) {
if (number === 1 return false;
elseif (number === 2) return true;
else return IsEven(number - 2);
}Now it does all positive numbers :laugh: EDIT: because I get serious reactions on this code The code above is how NOT to do it - it's satire.
No...only positive integers. Since this is JS, some jerk could pass a float in and get your recursive function to march off the negative end of the numbers.

Hmmm, you are right. The the improved improved version.
function IsEven(number) {
if (number === 1) return false;
else if (number ===2) return true;
else if (number > 2) return IsEven(number - 2);
else return IsEven(number + 2)
}Now it does negatives too ;P EDIT: because I get serious reactions on this code The code above is how NOT to do it - it's satire.

They've missed a whole set of entries for those that speak British style English. American: Thirty-Two Thousand One Hundred Twelve British: Thirty-Two Thousand One Hundred And Twelve I'd better get editing...
The AND denotes the decimal or fractional portion of the number. So Brits in the example above, Twelve whats?

And now this line of code is used: IsEven (4.2); It'll bounce around 0 until the heat death of the universe.

Not in British English (or just "English", as it's known). :) "One hundred and twelve" ===

The British English convention is to put an 'and' between any hundreds and non-zero tens/units and 'point' to indicate the fraction part. Therefore 123,456.789 is... "One hundred and twenty three thousand, four hundred and fifty six point seven, eight, nine"

And
0. Is0even or odd? How can we know when that code is lacking the answer to this most important question?Oh sanctissimi Wilhelmus, Theodorus, et Fredericus!
doesn't it throw an exception? :-\

I'm trying to guess what certain CPers would do if they were confronted with this person. JSOP - bullet in the guy's head to put both the guy and everyone else out of their misery. honey the codewitch - After she quit twitching, she'd write a parser to optimize the code. OriginalGriff - figures out how to turn it into a CCC clue Nagy - just wanders off, asking where the gin is. Me - I'd tell him to turn it all into a switch statement.

Me: Have Security dress the guy in a hazmat suit, and escort him out of the building. I'd then cordon off the area and decontaminate everything he touched on his visit - in an autoclave, by choice. This level of stupidity leaves traces wherever it goes.

Someone's already beaten you to that suggestion: [Feature Request] Support for British English "and" · Issue #85 · samuelmarina/is-even · GitHub[^] :-D
"These people looked deep within my soul and assigned me a number based on the order in which I joined." - Homer
Now the question is... Is the one with that request trolling him? Or does he really needs it for his usage?
M.D.V. ;) If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about? Help me to understand what I'm saying, and I'll explain it better to you Rating helpful answers is nice, but saying thanks can be even nicer.

Well, my comment on that issue requesting support for the Yan tan tethera[^] counting system was perfectly legitimate. :laugh:

With big number (I mean really big numbers), you will run into a StackOverflowException. What about "tail recursion"? :-D

At first I thought "Dang! I am looking for a package that determines if a number is odd." But it actually turns out that they have helpfully written one. Here it is if anyone else needs it -> odd numbers[^] A real godsend!

Just what I was looking for! My own isEven function only goes to 1000, this is a huge step forward :D Just need to brace it properly and remove all those function exits...
function isEven(number) {
let result;
if (number === 1) {
result = false;
}
else if (number === 2) {
result = true;
}
else if (number === 3) {
result = false;
}
// ...
return result;
}And they have an is-odd package which is consistent with this one too. As programmers we know how important it is to be consistent. Thanks for this great find! :thumbsup: :-D
