Vue's reactivity system currently does not support typed arrays.

Is it the same with ES6 Maps too?

Closing to track along in #2410 - we will likely only implement this when these new data types reach a significant support rate. Alternatively, we may ship a "mordern browser only" build that leverages ES2015 Proxy which makes supporting all these new data structures (including Map and Set) less hacky.
