Comparing NaN values for equality in Javascript

Question

I need to compare two numeric values for equality in Javascript. The values may be NaN as well. I\'ve come up with this code:

if (val1 == val2 |         


        

Answer 1

As long as you know these two variables are numeric, you can try:

if (val1 + '' == val2 + '')

It turns the two values into strings. A funny answer, but it should work. :)
