It explains the trend of programming language usage

Today, we explain about utilization ratio trends in programming language announced by TIOBE Software.
Look at the Graph, JAVA is the highest ratio in the present. However, it is slightly declining from 2002. On the other hand, Objective-C experiences a remarkable growth from 2010. As a reason for it, we assumed that Objective-C is used for Apple’s app such as iPhone or iPad.
In contract, PHP has been declining from 2010. We infer that PHP lose popularity from there is limitation of describing expressiveness even though PHP can easy develop and create dynamic data.
Near future, the popularity of Java script（JS） which has rich expressionistic abilities must be increase. Web industry trade would also need companies and people who has skills and know-how of Objective-C and JS.
