Regarding DOM methods

[Vivek Alampally]

Hi Can anyone here please explain me what does the following code do with an example?

while(node.firstChild)
node.removeChild(node.firstChild)

assume node is sth like var node=document.getElementById(id);

I know that it removes all the child nodes of a node represented by id="id". I dont know how a while loop works here.

Thanks
Vivek

while(node.firstChild){
    node.removeChild(node.firstChild);
}

It loops until there are no more children left.
