Scripting languages are great because they can do so much with so little. Therefore, Perl and Awk are a couple of favourites. What about JavaScript?<\/p>\n
Let’s say , in JavaScript, var z=-3. Then (z? 10:20) will return 10. If z=0 or z is undefined, (z? 10:20) will return 20. ?: makes up the JavaScript conditional operator. The question mark evaluates if z is true (assigned nonzero value). If true, the number before the colon is returned, which is 10 in this case. However, if z is 0 or null, the number after the colon, 20, is returned. An error is returned is z was never defined.<\/p>\n
Neat, eh?<\/p>\n
