JavaScript JavaScript Foundations Arrays Methods: Part 3

concat array challenge

Bummer! Was expecting a 'saying' array of 'The,quick,brown,fox,jumps,over,the,lazy,dog' but got 'The,quick,brown,fox,jumps,over,the,lazy,dog'.

Hum... so why does this say it's incorrect? I changed the var saying as follows: var saying = first.concat(second + ",dog");

The array concat() method tags a series of arguments separated by commas. So you need to replace the + symbol in your code with a comma, and remove the comma in the string ",dog" like this:

first.concat(second, "dog")

Thank you!
