javascript "2" "1" + 1 returns an error?
<p>I recently had a phone interview and was asked a question on javascript which is not my strong point but do have some really basic level understanding. The question was this:</p>

<p>What does <code>"2" "1" + 1</code> return?</p>

<p>At first glance I thought it would return an error because the syntax seemed incorrect. I just winged it and said it would return an error because at first glance it looks like there should be some type of "operator" between <code>"2"</code> and <code>"1"</code></p>

<p>Was I correct? Just looking at it I don't even understand what it's supposed to be returning because although I am really a beginner with javascript, it looks wrong to begin with.</p>

<p>So, does <code>"2" "1" + 1</code> in javascript return an error?</p>

<p>Thanks!</p>
