Node.js loop over variable and print it's values

Question

Is there a way to loop over the following variable and print out it's values (0,1,2) i've tried to run forEach on it, but i get an error that forEach is not a function.

let colors = {
RED: 0,
GREEN: 1,
BLUE: 2 };

Depending on what you mean by _"print out it's values"_, you might want to just use `console.dir` — James Thorpe, Jul 11 '17 at 11:08

var colorKeys = Object.keys(colors);

for(int i = 0; i < colorKeys.length; i++){
    console.log(colors[colorKeys[i]]);
}

Try it

let colors = {
RED: 0,
GREEN: 1,
BLUE: 2 }; 

for(let i in colors){
console.log(colors[i]);
}
