setInterval处理程序是否被视为内存泄漏？

Question

The javascript code:

function blah()
{
    var blahInterval = setInterval(function(){ 
        if( some_global_variable == 5 )
            clearInterval(blahInterval);
    }, 1000);
}

I have this code with multiple variants, and it is going to be called gazillion times in a NodeJS script. Shall I delete blahInterval; after clearInterval ?

Is this a memory leak? Or the GC will clean it once setInerval function goes out of scope?

Answer 1

The GC should clean it when it goes out of scope. As long as the if condition can be false to clear the interval. I would not consider it a memory leak.
