Why is this wrong? "good morning, students".length(); I would rather save it as a variable & then do variable.lenght();

I'm not sure I follow your question, but .length does not need the parentheses. 

let thisVariable = "Good morning, students";
console.log(thisVariable.length);
//returns 22
console.log("Good morning, students".length)
//returns 22

Hello Josh, The length works with strings and array for example

const a = [1, 2, 4, 45]
// a.length => 4
const myName = "JOSH"
// myName.length => 4

I wish my comment helped you you can check the documentation : https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/length
