It gives an error obviously the 1 + + '2' part is wrong
If we fix that then its going to output 122 which is C
The reason is javascript type conversion happens in a way that if the two values dont match it will just convert it to a string

Edit: I ran the code and voila it gave 122. Please if you do tutorials and such make sure its at least correct.

Output is 32.

Because if we add number and string, it will return output as string. In this case, we use type casting to solve the problem. If we use + operator before a string which holds a number, it will be converted from string to number.

Solution:

1+ +'2' This returns 3. Because Type casted.
After 3 concat with a string '2', it returns 32

So the solution is 32
