What is jQuery?
First, What Is jQuery?
Over the fifteen years since its initial development, jQuery has undergone countless updates to both build on the initial feature set, as well as to become tailored toward modern intensive programming fields like machine learning and AI and their various needs.
So How Does jQuery Actually Work?
jQuery is an example of a Document Object Model (DOM) manipulation library, which is a tree-structure visual representation of the various key elements that make up a given web page. jQuery’s main benefit is its ability to simplify the syntax used for finding, selecting, and manipulating DOM elements (thus, streamlining programming and navigation of a web site). This means that jQuery can be used to sort through a document for elements with certain properties, adjusting attributes for elements, or developing responses to various events that might result from a user interacting with the web page.
What Are The Principles Of jQuery Development?
Simplicity and Efficiency:
Any experienced programmer will tell you that the more logical, clear, and streamlined a programming tool is, the happier you’ll be when building something (especially complex apps and projects). jQuery promotes simplicity and efficiency through key features like “chainable” functions and shorthand function names.
Removal Of Cross-Browser Incompatibilities:
In what has become the norm for most popular modern development tools, jQuery offers extensive opportunities for programmers to customize and add functionality as needed. This means events, elements, and methods can be easily integrated with jQuery and then reused as a plugin.
What Are Some Other Advantages Of Using jQuery?
Aside from the structural benefits that jQuery offers programmers through its design principles, the jQuery library also offers benefits for a variety of common programming operations. Some of the most notable benefits include:
- The DOM, or Document Object Model, is a browser interface that specifically allows for the deletion, addition or updating of various HTML elements. jQuery makes this easier for programmers by offering an array of tools for doing so (specifically through methods like .replaceAll(), .remove(), .append(), etc).
- The jQuery .ajax() method streamlines sending asynchronous HTTP requests to the server without needing to reload the page. This is among many other convenient AJAX functions in the library, including .getJSON(), .load(), and .serialize(), each of which can be used regardless of the platform or the browser.
- Developers can build dynamic effects throughout their application by calling on the various jQuery animation methods such as .hide() / .show(), .slideUp() / .slideDown, and .toggle(). Even if the default animations don’t offer the exact functionality you might need, you can also use .animate() to create your own custom animations of many CSS properties, allowing for greater flexibility in design (as well as a better experience for end-users).
- Even better, since search engines are optimized for reading content, jQuery’s dynamic content is readable by most search engines since everything within the development tool is seen as text by them.
- Like many of the most popular development tools and frameworks, there are tons of resources throughout the Internet for further learning and collaborating around using jQuery. For example, the jQuery Learning Center is a repository of code and documentation submissions, which can help developers solve common programming problems and collaborate with other developers on challenges and best practices.
Is jQuery A Smart Thing For Me To Learn As A Beginning Developer?
- jQuery offers a far more simple syntax for making AJAX calls than the native XmlHttpRequest.
- jQuery also works on the server side with NodeJS, making it a good method for gaining familiarity with server-side development
- Because jQuery is a dependency for many libraries that beginners often use, learning jQuery can make operating a variety of development tools much easier
Are There Any Disadvantages To Using Or Learning jQuery?
Like any development language or tool, while jQuery has a significant number of benefits proven by its popularity among developers worldwide, there are still some downsides to using or learning the tool. Here are the most notable:
