Hiring a top-notch jQuery developer can be a game-changer for your web development process. jQuery is an open-source JavaScript library that’s designed to make those tricky JavaScript tasks a breeze. It simplifies coding and saves you tons of time. But here’s the kicker – jQuery isn’t always the smarter option over plain JavaScript. When you’re on the hunt for a remote jQuery developer, you need someone who’s not just good with jQuery but also a pro with JavaScript. This way, they can make your webpage fast, functional, and efficient, using the best tool for the job every time. So, read on to learn how to hire smart and ensure your developer has the chops to handle both languages like a pro.
What to Look For In A Remote jQuery Developer?
Finding the perfect remote jQuery developer can feel daunting, but it’s all about knowing what to look for. Here’s what you should focus on:
Technical Proficiency
Your ideal candidate should be a jQuery and JavaScript wizard, with solid experience in HTML5, CSS3, and AJAX. You want someone who can show off a killer portfolio, full of responsive, cross-browser compatible projects that demonstrate their skills and creativity.
Communication Skills
Communication is key in a remote environment, so look for developers who can clearly and effectively interact through tools like Slack, Zoom, or Microsoft Teams. They should be articulate and responsive, making collaboration seamless despite the physical distance.
Time Management
Time management is another crucial factor. The best remote developers are self-starters who can juggle multiple tasks, prioritize effectively, and meet deadlines without needing constant supervision.
Time Zone Compatibility
In a global workforce, time zones matter. Make sure your candidate’s working hours overlap with your core working hours to facilitate real-time collaboration and reduce delays.
Version Control Knowledge
Familiarity with version control systems like Git is a must for keeping projects organized and ensuring smooth teamwork.
Problem-Solving Skills
A great remote jQuery developer is someone who thrives on solving problems and can debug and optimize code efficiently.
UX/UI Design Principles
Look for candidates with a good eye for UX/UI design who can translate design mockups into functional web applications.
Continuous Learning
The best developers stay up-to-date with the latest industry trends and technologies, showing a willingness to learn and adapt.
Best Technical Interview Questions To Ask your jQuery Developer
When it comes to hiring a jQuery developer, asking the right technical questions during the interview is crucial. Below are some of the best technical interview questions to ensure you find the ideal jQuery developer for your team.
1. Explain $() in the jQuery library
This is an elementary, common function used within jQuery, so your potential employee should certainly know what it means. Essentially, $() wraps any object into a jQuery object. This is important because, from here, you can call different methods defined jQuery objects.
Although this question is basic, it helps prove if the developer you’re interviewing truly knows jQuery.
2. How can you select each <div> element on your page using jQuery?
If you want to hire a jQuery developer, they should be well versed in the selectors supported in jQuery, such as the ID selector, class selector, and tag selector. If you only give your future coder the information in this question, they should know to use a tag selector to select each div element.
The simple code $(“div”) will return a jQuery object that contains all of the div tags on the page.
3. How can you create a clone of any object with jQuery?
jQuery provides a clone() method that copies all matched elements in addition to all of their descendant elements and text nodes (also referred to as a deep copy).
Check out this example of the code required to clone an object using jQuery:
<!-- wp:paragraph -->
<p>$(document).ready(function() {</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>$(‘#btnClone’).click(function() {</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>$(‘#dvText’).clone().appendTo(‘body’);</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>return false;</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>});</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>});</p>
<!-- /wp:paragraph -->4. How do you attach an event to an element that should be executed only once?
This is possible via the jQuery one() method by attaching a handler to an event for the given element. The handler has then executed a maximum of one time per element, meaning that the related function is only called once.
Here’s some example code to better check to make sure your interviewee understands this question:
<!-- wp:paragraph -->
<p>$(document).ready(function() {</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>$(“btnDummy”).one(“click”, function() {</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>alert(“This will be displayed only once.”);</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>});</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>});</p>
<!-- /wp:paragraph -->5. Explain the $(document).ready() function and when you should use it
This question is another important one that interviewers should ask before they hire a jQuery developer. Essentially, ready() executes code once the document can be manipulated. Using the ready() function with jQuery, your code can be executed only when the DOM is fully loaded and ready.
This should function in all browsers, as jQuery takes care of the problems of cross-browser execution for you. Here’s an example of this code:
<!-- wp:paragraph -->
<p>$(document).ready(function() {</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>console.log(“ready!”);</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>});</p>
<!-- /wp:paragraph -->6. Name some of the most common methods used to get and set information about elements. Add one code example changing the inner HTML or attribute of an element.
While there are many different ways to change an existing element, this question focuses on changing the innerHTML or attribute of an element because it is one of the most common and essential to know.
Below are some of the most common methods to get and set information about elements:
<!-- wp:paragraph -->
<p>.html() - Get or set the HTML contents.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>.text() - Get or set the text contents; HTML will be stripped.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>.attr() - Get or set the value of the provided attribute.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>.width() - Get or set the width in pixels of the first element in the selection as an integer.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>.height() - Get or set the height in pixels of the first element in the selection as an integer.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>.position() - Get an object with position information for the first element in the selection, relative to its first positioned ancestor. This is a getter only.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>.val() - Get or set the value of form elements.</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>While it might seem trivial to change things about elements, your potential developer needs to know that the change affects all elements in the selection. If they only want to change one element, it has to be specified. Here’s an example of changing the HTML of one element:</p>
<!-- /wp:paragraph -->
<!-- wp:paragraph -->
<p>$(“#myDiv p:first”).html(“New <strong>first</strong> paragraph!”);</p>
<!-- /wp:paragraph -->Get Ready To Hire Your Remote jQuery Developer
