Online staffing firm Freelancer.com reported jobs involving website development and internet applications rank among the fastest-growing jobs on its platform, according to Freelancer.com’s quarterly report. The report also said social media-related jobs and creative skills surged sharply in popularity.

Freelancer.com based its report on an analysis of nearly 500,000 jobs posted in the third quarter.

React.js, the open-source JavaScript library often employed to develop user interfaces for mobile applications or single page applications on the web, ranked second in terms of growth during the quarter.

In addition, ASP, which stands for “active server pages” and topped the Fast 50 in the prior quarter’s report, ranked third and appears to show no sign of slowing, according to Freelancer.com. ASP is an older technology usually run on a Microsoft web server that allows web developers to create more dynamic and interactive websites.

Marketing jobs posted during the quarter well exceeded the social networking jobs posted during the period, reflecting the broader popularity of Facebook marketing as a job category. Creative jobs involving digital tools such as Adobe Photoshop and Illustrator editors were also among the faster-growing broad skills areas on the marketplace during the quarter.

On the flip side, jobs involving mathematical skills have seen a sharp swing downward.
