Are you trying real hard to make up your mind whether learning any particular programming or scripting language is worth the effort? Why not head over to Indeed and have a look at their compilation of most recent stats about the job postings awaiting coders? You can get your first glimpse right here.
As of today, among the fastest growing keywords found in online job postings are, quite predictably, HTML 5, MongoDB (still a tiny market by numbers), iOS, and Android. By percentage in all job posting containing the search terms, these keywords/languages all stack up and grow pretty well.
In relative terms, it is a different story. HTML 5 outpaces everything else, but since it’s easy to learn, it may not be enough of a reason to get hired. If you had to choose between iOS and Android development, it seems a no-brainer. While similar in absolute terms at less than 0.5 percent market each, the growth in job postings for Android development is shooting through the stratosphere compared to iOS. Your dream job may well involve both these platforms, but Android skills will probably get you there faster.
