Need Help Understanding Simple Function

Solar2D General Questions/Discussion
#1

Hi, I’m going over some code, and I came across a function I’m having trouble understanding.  Here it is, firstly:

local o = display.newGroup(); o.getStagedataByStageId = function(value) for i=1, #\_G.stages do if \_G.stages[i].stageId == value then return \_G.stages[i]; end end return \_G.stages[1]; end 

I believe this function’s purpose is simply to return a value, but what I don’t understand is that there are two return statements.  Because it’s read last, wouldn’t the one on the bottom override the previous return statement (the one in the if/then statement), making that statement redundant?  In my head, I’m thinking (incorrectly of course) it should say something like:

if\_G.stages[i].stageId == value then return\_G.stages[i]; else return\_G.stages[1], end 

 I’m not an experienced coder, so I’m sure this question is very noobish.  Can anyone help me understand?

 

Thanks in advance,

Steven

The “return” statement in the IF/Then statement would execute if the statement was true and the exit the function. The last “return” statement would only execute if the IF statement was false.
