It's not the console, it's Array#toString, which calls Array#join with no arguments, so Array#join defaults the separator to ",". Array#toString is being called because you're using + on a string and an array, which will coerce the array to string before doing the concatenation.

Example using join explicitly:

var str = ['apple', 'orange', 'banana', 'strawberry'].join();
console.log(str);
