How to know if a node is already checked out, who checkedout

[sam4alf]

I am writing a custom webscript to display a list of documents inside folder. I want to display checkout status and the checkout username. Based on these details, I want to enable, disable some buttons.

For this, how do I know if a node is checked out? I tried all of the following:

node.isCheckedOut == true
node.checkout == true
node.checkout == 1

Where I can find all the available methods/properties on a javascript node?

Thanks,
Sarma.
