programming languages - It's considered a bad pratice use return to end a function? -

i'm php , actionscript developer, , in of functions use return end it. example:

private function lolsome(a:string):void {    if(a == "abs"){return void;}     // function's code       } 

i place function's code else, prefer way because in opinion, more legible. want know if considered bad practice or that.

thanks!

i consider bad practice if have returns inside long complicated functions because can harder else understand algorithm when looking @ it. however, bad practice have big long functions in first place (they should split multiple smaller functions).

overall, consider validating parameters , state @ beginning of function , returning practice, not ok.

but still careful not litter function several different returns within main logic.
