Combine Two Arrays Using the concat Method |
Combine Two Arrays Using the concat Method
- The concat method is used to join two or more arrays or strings.
- This method does not mutate the existing arrays, but returns a new array.
Solution
function nonMutatingConcat(original, attach) {
// Add your code below this line
return original.concat(attach);
// Add your code above this line
}
var first = [1, 2, 3];
var second = [4, 5];
nonMutatingConcat(first, second);
