Javascript console.log(object) vs. concatenating string

Question

I\'m running this in node.js:

> x = { \'foo\' : \'bar\' }
{ foo: \'bar\' }
> console.log(x)
{ foo: \'bar\' }
undefined
> console.log(\"hmm: \" + x)
         


        

Answer 1

The + x coerces the object x into a string, which is just [object Object]:

The pretty printing is a very nice and probably very complex underlying code that someone implemented as part of the console object and the log method.

Try this:

console.log("hmm: ", x);
