Can someone help me understand why my answer to this challenge passed, i think i understand the concept of this challenge , however i don’t understand how i ended up with the answer in my code ? my understanding is that the challenge was to combine the two arrays into one, what i don’t understand is how i ended up with 43 in my array.
`const myConcat = (arr1, arr2) => arr1 + arr2;
// test your code
console.log(myConcat([1, 4], [3, 4, 5]));
