Im learning JS by analyzing a to-do list tutorial and I'm stuck trying to fully understand the functions that clears a populated list by clicking a button. I think I understand this small script but not sure.

    `function clearTaks(){
        while(taskList.firstChild){
            taskList.removeChild(taskList.firstChild);
        }`

I think that the condition while(taskList.firstChild) means that meanwhile taskList still has a Chidren, keep doing... but I wonder why that works without any other value. I mean, shouldn´t it be something like this?: while(taskList.firstChild != false) or something similar. Thanks in advance for your help
