String literal first or second in concatenation?

  • A+

In JavaScript, is there any circumstance where there is a semantic difference between these two options? + '' 


'' + 

I would've expected the latter to more reliably coerce the result to a string, but I can't find any discussion of this (after much Googling) nor any example where it seems to matter.


Both are the same.

There is only a difference if there are other + (on the left or the right). In other words:

1 + 1 + ''                          // results in '2' 

Is not the same as:

'' + 1 + 1                          // results in '11'
