Review the code in app.js. Use the log method on the console object to print out the name variable.

please help me out with this , it's making me crazzy

app.js 
const name = "Andrew";
const details = { favouriteLanguage: "JavaScript", age: 33, children: 3 } 
const errorMessage = "Something bad has occurred";

console.log(name: " Andrew");
console.dir({favouriteLanguage: "JavaScript", age: 33, children: 3});
console.error("Something bad has occurred");

This line has a syntax error -- sometimes a fresh set of eyes on your code can see things that hide from the programmer.

Good luck with JavaScript!

console.log(name :"Andrew"); console.dir({favouriteLanguage: "JavaScript", age: 33, children: 3}); console.error("Something bad has occurred");

Still can't get it right though.

In order to pass the Challenge-- you need to understand the three console methods (log, dir, and error) and syntax. These are very basic tools for debugging and need to be understood. I would rewatch the preceeding videos if you did not understand what these commands do as Node.js is pretty complex and takes quite a bit of practice to be successful.

console.log() which is documented here: https://developer.mozilla.org/en-US/docs/Web/API/Console/log

console.dir() which is documented here: https://developer.mozilla.org/en-US/docs/Web/API/Console/dir

console.error() which is documented here: https://developer.mozilla.org/en-US/docs/Web/API/Console/error
