Title: Check for config via NOT

Until yesterday, this was `if (config == null)`, which checks for a certain
falseyness of `config`. This was changed yesterday to `if (config === null)` which
checks if `config` is, in fact, `null`. The problem is that when calling a function
without a parameter, then the paramter is `undefined`. So maybe we should check
for `if (config === undefined)` but I figure its easier and clearer to check
`if (!config)`
