Troubling getting ID of a structure.

[Kap]

Hey, having trouble with the code below. It's the -> container.id that's always undefined.

            for (let source of sources) {
                let containers = source.pos.findInRange(FIND_STRUCTURES, 1, {
                    filter: s => s.structureType == STRUCTURE_CONTAINER
                });

                for (let container in containers) {
                    if (_.some(creepsInRoom, b => (b.memory.containerId == container.id && b.memory.role == 'lorry'))) {
                        continue;
                    } else {
                        name = this.createLorry(30, container.id);
                        break;
                    }
                }
            }

This code below does almost the same, but here the container.id is never undefined.

        for (let source of sources) {
            let containers = source.pos.findInRange(FIND_STRUCTURES, 1, {
                filter: s => s.structureType == STRUCTURE_CONTAINER
            });

            for (let container of containers) {
                if (_.some(creepsInRoom, c => c.memory.containerId == container.id && c.memory.role == 'miner')) {
                    continue;
                } else {
                    name = this.createMiner(source.id, container.id);
                    break;
                }
                
            }
        }

Hope someone can help me out, thanks!

Looking IN the Array, you are, when looking OF the Array you should.

IN is for objects. OF is for arrays.

Cheers for that!
