[JAVASCRIPT] Code not returning sub-array in array [CLOSED]

Question

I've been coding this on CodePen and it should return [[value], [value], [etc],[etc]] but it returns just an array. Am I doing something wrong, or it's just our play ground?

Answer 1

actually it works xD
use JSON.stringify
alert(JSON.stringify(end));

when you simply print the array it is printed spreaded
stringify will convert it to a string and display it as it really is

you can also print its length and see that the element count has changed

Answer 2

also you can add the following check
if(arr.length%size!==0){
return;
}

to prevent results with the last subarray on a different size than you expect

Answer 3

not sure why
something with yhe way SL playground compiler works i guess

Answer 4

np 😉

Answer 5

wow. ok. Thank you, Burey. CodePen shows me the subarray directly because it has json embedded?

Answer 6

Thank you very much. Really appreciated.

Answer 7

those challenges were good for practice, I've solved that as https://code.sololearn.com/WWMpp3f98h7g/?ref=app and recently finished the three series, basic intermediate and advanced, algorithms, good practice
