Console returning [Object object] instead of object members

Question

I was trying to build myself a small function to simpifly logging to the console in JavaScript. But for some reason it doesn't log the properties of the object, only the type of the logged object ([Object object].

<!-- language: lang-js -->

var randomObject = {

    fistname:"peter"
};

function log(message,color){

    var color = color || "green";

    console.log("%c" + message, "color:" + color + ";font-weight:bold; font-family:'Helvetica Neue'");

}

log(randomObject);

i'm grateful for any help/explanation

You are converting an object to a string by doing concatenation,

"color:" + color .....

When you attempt to do so, the primitive value of the object will be returned and concatenated with the target string.

If you want to print the object in a string format then use JSON.stringify(color).

console.log("%c" + message, "color:" + JSON.stringify(color) + ";font-weight:bold; font-family:'Helvetica Neue'");
