I've a code:

a=function(x){alert(x)}
b=function(x){document.write(x)}
c=1;
[c==1?a:b](':p');

but it's not working. Is possible to do what I want?

• 3 Why do people like to write such unreadable code? For goodness sakes, use an if/else and make your code reaadable. If you want small size, then minimized it afterwards. My priorities are "correct", "readable/maintainable", "pact", "fast". Only on a very few occasions (usually after detailed performance profiling) is it worth sacrificing either of the first two for speed or size. – jfriend00 Commented Dec 9, 2013 at 17:47

Yes, just replace the square brackets with parentheses. You are creating an array literal, but you want to isolate an expression:

(c==1?a:b)(':p');

This would also work, but there is no reason to use it:

[c==1?a:b][0](':p');
