The Tiobe Programming Community Index rankings show that JavaScript's popularity as a programming language is on the rise. It has recently risen in to the top 10 of popular programming languages based on searches on the web. This article outlines the top 10 languages and goes over how the chart is tabulated.
Given the line of work that we are in here at Crank, it's actually surprising that JavaScript isn't higher. There seems to be a movement towards the language as a way of providing content to end users, and given the importance of the internet and it's content to everyday life, JavaScript should be more of an integral part of the programming culture.
One theory as too why JavaScript isn't higher is that it is fairly well known, and therefore there aren't a lot of searches performed about JavaScript. That may be a weakness in the way that the Tiobe Programming Community determines it's rankings.
