Is there any particular reason to use both, `querySelector()` in one line, and `getElementById()` in the second one, to achieve the same thing (selecting the node by it's `id`)? If we don't want to select complex DOM structure please use `getElementById()`, it's 99% faster according to the newest jsPerf tests ([link here](http://jsperf.com/getelementbyid-vs-queryselector/11)):
