afaik i already translated it to lite-c.

also

define max_nodes 300; // maximum number of nodes that can be used in this demo
define max_arrays 90000; // 300 x 300 (max_nodes * max_nodes)

would be

var max_nodes=300; // maximum number of nodes that can be used in this demo
var max_arrays=90000; // 300 x 300 (max_nodes * max_nodes)

not the one you did.
