I am editing various js topics and comparing support in various browsers.

caniuse.com lists the follow browser vendors.
      IE Firefox Chrome Safari Opera iOS Safari Opera Mini Android Browser Blackberry Browser IE Mobile 

However Opera has a Presto and a Webkit versions. 

About Opera

System Windows 7 
Browser identification

Opera/9.80 (Windows NT 6.1; WOW64) Presto/2.12.388 Version/12.17

Opera Next 19.0
Made to discover

Version information
      Version: 19.0.1326.45 - Downloading update 44% 
      Update stream: Next 
      System: Windows 7 64-bit (WoW64) 

Browser identification

It appears to me that Opera Next should be used for browser comparison, on the assumption that the Presto engine is being phased out.

the latest Presto engine release also recognizes webkit prefixed CSSDOM properties and webkit methods, but comparison between the two versions of ‘Opera’ are worlds apart.

Regards and Greetings from Australia.
