' Dragonflies ' (dragonfly) eat bugs (bug), and that's exactly what we want Dragonfly to do for developers around the world, ' said David Storey, director of developer relations. of Opera.

Dragonfly is not a debugging tool in the first browser. Mozilla has the Firebug tool, and Google's Chrome browser also has several built-in feature checkers. Dragonfly also has the ability to debug websites on smartphones, TVs and other devices, by including these errors on the developer's computer.

In the field of open source development over the last 5 years, Dragonfly has been designed to help website designers control increasingly complex web sites and applications.

' We have entered an era when JavaScript is popular, and Ajax is a common term everyone is talking about. Creating complex web applications without such tools will be difficult to support Opera on those services, "Storey said on the Opera website.

Opera's Dragonfly tool can debug JavaScript code and can be used to control the DOM (Document Object Modules), CSS (Cascading Style Sheets) and HTTP protocol packets. This tool includes a console that identifies the errors, and a command line.

With the JavaScript debugging tool, developers can monitor specific parameters or isolate the operation of a particular expression. Network testing tools can be used to debug a slow startup site, by looking at resources while they are downloaded.

In addition to JavaScript and related Ajax technologies, this debugging tool also supports HTML5 and the next generation related standards like SVG (Scalable Vector Graphics).

Dragonfly 1.0 is available in the latest version 11.1 of Opera browser.
