how to stop execution in lightning component?

Hi all,
in my lightning controller i want to stop execution after displaying error.
but right now after displaying error it moves further.

Anyone know how to stop execution

In below code i am comparing two dates 
var fromCmp = component.find("From_date");
var fromCmpval = fromCmp.get("v.value");
var toCmp = component.find("To_date");
var toCmpval=toCmp.get("v.value");



if (fromCmpval > toCmpval) 
                {
                  
          toCmp.set("v.errors", [{message:"To Date should be Less then To Date"}]);

//here i want to stop execution after displaying error
               }


Thanks in advance.

Hi Shruti,
You just need to add a line after error message:
return false;

I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.
