Try/catch oneliner available?

Question

Just as you can convert the following:

var t;
if(foo == "bar") {
    t = "a";
} else {
    t = "b";
}

into:

t = foo == "bar" ? "a" : "b";

, I was wondering if there is a shorthand / oneline way to convert this:

var t;
try {
    t = someFunc();
} catch(e) {
    t = somethingElse;
}

Is there a method of doing this in a shorthand way, preferably an oneliner? I could, of course, just remove the newlines, but I rather mean something like the ? : thing for if.

Thanks.

Answer 1

You could use the following function and then use that to oneline your try/catch. It's use would be limited and makes the code harder to maintain so i'll never use it.

var v = tc(MyTryFunc, MyCatchFunc);

tc(function() { alert('try'); }, function(e) { alert('catch'); });


/// try/catch 
function tc(tryFunc, catchFunc) {
     var val;
     try {
        val = tryFunc();
     }
     catch (e) {
         val = catchFunc(e);
     }
     return val;
}
