Google today released a new browser based console where you can write and simultaneously test applications that use any of the Google AJAX APIs including maps, search mashups, blogs feeds and more.
The programming console, known as AJAX APIs Playground, provides sample starter applications for all Google APIs but you are free to change the source code and save the modified version to your own Google Account for referencing later.
You can experiment with all functions / methods available in Google APIs and hit the Run button to display the responses in real time much like the Yahoo! Pipes interface.
Google’s AJAX API console will definitely save developers some time as they can validate and test their code right inside the browser without having to write code in local HTML files.
