Inside Google, Javascript is the 4 largest language (in terms of lines of code) but one the fastest growing. Developing fast, robust and high quality Javascript is however a challenge within the industry. Unlike C++ or Java, the availability of high quality development, debugging and testing tools for Javascript is still lagging industry standards.

Google has developed several unique tools to help address this issue, and make JavaScript developers more productive, both in developing and testing Javascript code. In this video, Cory Smith, the main engineer behind JsTestDriver, explains how he approached the problem and what tools he developed for addressing some of these issues.
