 <code>
     ("foo" + + "bar") === "fooNaN" // true
-</code>    
+</code>
+
+**Explanation**
+1. `+"bar"` calls `"bar".valueOf()` which tries to return a number
+2. Because "bar" is a string, it returns `NaN` instead
+3. `"foo"` is concatinated with `NaN`
+4. Because of the concatination `NaN.toString()` is called which results in `"foo" + "NaN"`
