jQuery Developers Hiring Guide

The “Write Less, Do More” Library

“Write less, do more.” That’s the tagline of jQuery, a small, concise JavaScript library primarily used for web development. 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 for a JavaScript developer who is proficient in jQuery 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.

    Job Description

What is jQuery?

jQuery was initially created to support JavaScript developers with Internet Explorer development, helping them build websites that would run on the most common browser in existence at the time. Now, it remains a fast, lightweight tool for streamlining interactions between JavaScript and Document Object Model (DOM). In other words, it simplifies interactions between the language and an HTML/CSS document.

What does a jQuery developer do?

jQuery developers are JavaScript developers who use the library to create frontend features on websites and web applications and extend the functionality of their products. In order to achieve success, they must be highly skilled at and versed in jQuery, which supports their development efforts.

How popular is jQuery?

jQuery is used by approximately 78.1% of all websites. Because so many developers use the library, finding a skilled JavaScript developer who uses and has knowledge of jQuery isn’t too difficult.

What is event handling?

Event handling refers to user actions or changes that occur within the browser. The developer may create event handler code to respond or execute the appropriate function when the specific event occurs.

What is AJAX?

AJAX stands for Asynchronous JavaScript and XML. It enables an exchange of data without the user refreshing or reloading the page or browser. It’s a very useful tool, and fortunately, jQuery has plenty of support for this tool.

jQuery offers a number of methods for sending AJAX requests and generally handling the associated capabilities.
