Use a Ternary Operator!

Ternary Operator(53Characters):

i===1?doOne():i===2?doTwo():i===3?doThree():doNone();

If(108Characters):

if (i === 1) {
doOne();
} else if (i === 2) {
doTwo();
} else if (i === 3) {
doThree();
} else {
doNone();
}

Switch((EVEN LONGER THAN IF!?!?)114Characters):

switch (i) {
case 1: doOne(); break;
case 2: doTwo(); break;
case 3: doThree(); break;
default: doNone(); break;
}

this is all you need! it is only one line and it is pretty neat, way shorter than switch and if!
