Recently, a popular question has appeared on Stack Exchange: What are the biggest headaches for web developers? It turns out it's not about compatibility as everyone usually thinks, it's about HTML5.

Among all technologies related to front-end development, such as JavaScript, CSS3, HTML5, etc., which technical area 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 rapidly rising

Looking at the three most popular Web technologies (JavaScript, HTML5, CSS), JavaScript is still the topic that developers are most concerned about. But on Stack Exchange, the number of questions related to HTML5 and CSS is also rising rapidly. The researchers said: "In the future, they hope that the share of these topics will continue to rise."

Browser compatibility issues are getting fewer and fewer

The researchers found that cross-browser compatibility issues remain a popular topic, but the number of questions on the topic has dropped significantly over time (since 2009). This is mainly due to more and better JavaScript libraries, such as jQuery, and browser manufacturers' compliance with W3C standards.

The new features of HTML5 and JavaScript bring a lot of troubles to developers

On Stack Exchange, the number of questions about new features and elements of HTML5 and JavaScript (such as localStorage) has been relatively stable and is on the rise. 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, the researchers found that most of the questions about HTML5 since 2009 are mobile-related, such as device detection, local storage, etc., and the number of questions about CSS3's viewport meta tag is also increasing. These findings fully illustrate the more important role of Web technology in the mobile field. (Compiled by: Zhang Hongyue Editor: Xia Mengzhu)
