javascript - jQuery .each() not iterating over array of strings as expected - Stack Overflow

Doing:

var tags = ["foobar", "hello", "world"];

$.each(tags, function(tag) {  
  console.log(tag);
});

Gives me an output of

0    
1   
2

Why is my output not

foobar   
hello    
world

Do this, the first parameter is for index:

$.each(tags, function(index, tag) {  
  console.log(tag);
});
