Alternatively, yes you ca do it the way we are dealing with different browsers: have a map of internal representation to actual one. In general it can be represented as: ``` javascript function get_node_ver() { // some decisions and return as `06` for `0.6.x`, etc. } var EVENTS = { '06': { exit: 'death', // ... }, '08': { exit: 'exit', // ... } }; EVENTS = EVENTS[get_node_ver()]; ``` -- Sincerely yours, Aleksey V.
