I need help with this code challenge, seems really easy but I'm stuck

I don't understand why I'm missing

app.js 
const numbers = [1,2,3,4,5,6,7,8,9,10];
let times10 = [];

// times10 should be: [10,20,30,40,50,60,70,80,90,100]
// Write your code below
numbers.forEach(number => {
    times10.push
});

console.log(times10);

Hi Gerado,

You're almost there, but inside your forEach method, you're not pushing anything! This would be equivalent to writing console.log with no arguments. Nothing would happen. push() takes one argument - the item you want to push onto the stack.

Once you fix your code so you're pushing something, make sure you're pushing the right thing. Remember what the challenge is asking you to push. Just think about the very first time through, and what you want to be in the first position of the array. How do you get that in there, using the local number variable, which will be the first item in numbers (the first time, anyway).

Happy coding :sparkles:
