Could someone please explain this JavaScript answer?

This was a question in a JavaScript challenge quiz: What is the output of this code? var name1 = "John"; var name2 = "Sebastian"; console.log(name1.length + "" + name2.length); I am thinking the answer would be 13...however the answer was 49. Why? Could someone please explain?

it is using your value as a string and performing concatenation function
