Console log not showing anything in javascript

#1

I’m doing the javascript challenges and trying to output the value of variables to debug, but doing console.log(myVar) in the code and the dev tools console isnt showing anything.

(Edit: Yes I did open the dev tools console.)

(Edit: My code is
function largestOfFour(arr) { console.log(arr[0]); return arr; } largestOfFour([[4, 5, 1, 3], [13, 27, 18, 26], [32, 35, 37, 39], [1000, 1001, 857, 1]]);)

What is going on?

Did you open the console in your browser (using DevTools or similar)? The results window in FCC does not currently support console.log()

It sounds like your statement isn’t being reached. What is your code?

`
function largestOfFour(arr) {
console.log(arr[0]);
return arr;
}

largestOfFour([[4, 5, 1, 3], [13, 27, 18, 26], [32, 35, 37, 39], [1000, 1001, 857, 1]]);
`

@KimThibault If you are using FireFox are you using Firebug add-on? It is better than the native debugger i.m.o.

Of course you could always try http://pythontutor.com/visualize.html#mode=edit to visualize your code in action.
It works by the way.
