On line 18, set the variable 'saying' to the concatenation of the 'first' and 'second' arrays with the word "dog".

var first =  ["The", "quick", "brown", "fox", "jumps"]
var second =  ["over", "the", "lazy"];
var saying = (first.push(dog)).concat(second);

The concat method accepts numerous values as parameters.

So the dog should go as the second parameter of the concat. You also don't have a variable dog, it should be a string literal, like this: "dog".

And you don't need .push at all. 

var someArray = anArray.concat(anotherArray, "some string");
