“Write less, do more.” That’s the tagline of jQuery, a small, concise JavaScript library primarily used for by JavaScript development companies. Released in 2006, the library increases efficiency for developers, streamlining and simplifying the development process.
While technically a library, jQuery is also commonly considered a framework. Despite the fact that React.js surpassed it as the “most commonly used web framework” according to Stack Overflow’s 2021 Developer Survey, it remains an overwhelmingly popular choice for JavaScript developers.
Today, businesses like GitHub, Google, IBM, LinkedIn, Microsoft, Netflix, Reddit, Slack, Twitter, Uber, and Upwork, among many others, all have jQuery in their stacks.
Are you looking to hire jQuery developers to build, modify, and improve your web pages and web applications? Given the library’s enormous popularity, these professionals aren’t in short supply — but you still need to do your due diligence when searching for the candidate with the right qualifications.
