HTML5 has become the technology that Web developers are most concerned about

Among all the technologies related to front-end development, such as JavaScript, CSS3, HTML5, etc., which technical field is the most frequently discussed by web developers in private? Understanding this problem can better understand what challenges we are currently facing in the field of Web technology? To find out, the University of British Columbia conducted research on "questions commonly asked by web developers." They checked more than 500,000 technical questions related to JavaScript, HTML5, CSS and other Web-related questions on Stacke Exchange, analyzed the answers to these questions, and summarized which questions developers were most interested in and frequently asked. , summarizes the challenges that web developers currently face.

　 JavaScript is still king CSS and HTML5 are rising rapidly

　On Stack Exchange, the number of questions about new features of HTML5 and JavaScript and new elements (such as localStorage) has been relatively stable, and there is an increasing trend. Researchers say even expert-level programmers will be confused by the new features added to HTML5 and JavaScript, and they need better API support for these new features.

　The importance of Web technology in the mobile field has become increasingly prominent

Finally, researchers found that since 2009, most of the questions about HTML5 are related to mobile, such as device detection, local storage, etc., and about the viewport meta of CSS3 The number of labeling issues is also increasing day by day.
