so something like...

Function = function (room) {
    if (global.Cache.rooms[room].FunctionName === undefined) {
        if (global.Cache.rooms[room] === undefined) {
            if (global.Cache.rooms === undefined) {
                if (global.Cache === undefined) {
                    global.Cache = {};
                }
                global.Cache.rooms = {};
            }
            global.Cache.rooms[room] = {};
        }
        global.Cache.rooms[room].FunctionName = FunctionCode;
    }
    return global.Cache.rooms[room].FunctionName;
}

?
is there a way I could format that better? more readable etc.?

Any suggestions on customization or setup of your preferred IDE for screeps?

planing on doing a full rewrite of my AI and was thinking of swapping IDE to do it, (had just been using the in game environment) what are some suggestions?

I have an expensive function that returns a variable result.
I only want to call this function once per tick but want to access and change the result multiple times per tick.
What are some recommendations on how to achieve this?

That seems to be working thanks!
though now I will need to figure out how to generalise the script

When I spawn a creep using this function it isn't having role: 'hauler' assigned to its memory,
The creep will build but wont have anything in memory.

for (spawn in Game.spawns){
var spawn = Game.spawns[spawn];
if (Memory.buildList.length){
for (var i in Memory.buildList){
var blueprint = Memory.buildList[i];
var body = blueprint.body;
if (!spawn.canCreateCreep(body)){
console.log(spawn.createCreep(body,null,{role:'hauler'}));
Memory.buildList.splice(i,1);
};
};
};
};
