匿名函数的Javascript结果或

Question

is it possible to get the result of an anonymous function like so:

myarray[myelement] = myarray[myelement] || function() { return "result" };

Basically i want to assign the value of the function if the array element does not exist

Answer 1

Invoke the function using () :

myarray[myelement] = myarray[myelement] || function() { return "result" }();
