javascript statement syntax

Question

I have a statement in my script like this:

if(some condition)
{
 false;
 //rest of code
}

I am not getting the meaning of the false; statement as standalone statement.

This seems strange. Could you show the exact code instead of a simplified one to see if there's some reason to it? — koopajah

It appears to be a totally redundant statement, and will have absolutely no effect on the execution of the code. — Anthony Grist

false is a value, thus it has no effect. It is like writing 23 or "hi"... — Salvatorelab

This statement is simply totally useless.

The whole code you show does nothing if some condition has no side effect.

It's probable somebody forgot something, like a return.

You need to either return the value from a function, or assign it to a variable.

For example:

function myFunction()
{
    if(some_condition)
    {
        return false;
    }
}

or

var my_var;
if(some_condition)
{
    my_var = false;
}
