Comment:

 Seems there are two ways this can be optimized:
 1. Get the new or modified nodes `textContent` and do `twemoji.test()`
 before running `parse()`. That is still a big regex but will be much
 faster in case there are mo emoji chars.
 2. Implement something like Underscore's `_.throttle()` that will execute
 as soon as called but delay the next execution by 100ms -- 200ms.
