[removed] compare variable against array of values

Question

In javascript I am doing the following which works fine.

if (myVar == 25 || myVar == 26 || myVar == 27 || myVar == 28)
 {
   //do something
 }

Answer 1

Other way :

myVar = (myVar == parseInt(myVar) ? myVar : false); //to check if variable is an integer and not float
if ( myVar >= 25 && myVar <= 28){}

Edit based on the comment of Anthony Grist

This way works if you know what those values are going to be (i.e. they're not dynamic) and your array contains a series of consecutive numeric values.
