exit() in js?

is there a similar exit function in javascript as it is in php? For instance, when an exit function is called in php, the entire line of code below are ignored. Is there a way to accomplish this in javascript? Thanks

 

i guess there is no such a way you can exit(). but you may keep the code in :
if(<var>!=<your desired output>){
<here goes your entire body>
}

and you can get your output.
if the condition does not matches, the program will just end as there is no else statement and "}" is the last statement of your program.

 

use return and you can exit a function

 

Just do:
return;

 

Thank you all

 

As I know return is allowed only inside a function.

 

Thanks very much!
