javascript - Replace normal function with an anonymous function -

how use anonymous function replace normal function accepts this , returns results? please describe how variables being sent , anonymous function.

for instance, replace:

function myfunc(myprop){return [1*myprop,2*myprop,3*myprop];}  this.myprop=2; var myarray1=myfunc(this.myprop);

with like:

var myarray2=function(){return [1*this.myprop,2*this.myprop,3*this.myprop];}

this maybe want:

var myarray2=(function(myprop){                 return [1*myprop,2*myprop,3*myprop];}              )(this.myprop);

so here define anonymous function(because doesn't have name) , call immediately. this.myprop passed argument.
