|Usage||Implementing any interactive features you can think of within a web page/ app||DOM traversal, basic animations, widgets, and AJAX calls|
|Coding||You have to write the entire script from scratch||Predefined methods within the library reduce code length|
|Managing Interactive Events||Code needs to be written for animations, AJAX calls, DOM traversal, etc.||There is an existing jQuery method for nearly every interactive event|
|Performance||Faster since it’s directly interpreted by the browser||Slower since the library has to be downloaded first|
|Maintenance and Reusability||Can be done with user-defined functions||Reusable by its very nature|
Have you ever been to a webpage and wondered how all the fancy tech actually works behind the scenes? Interactive menus, widgets, pop-ups, forms, bars, charts, etc. are common elements of modern web design. And we seem to take them for granted.
First, they teamed up with Sun Microsystems to embed Java within their browser. Then, they hired Brendan Eich to integrate the Scheme language into Netscape Navigator. Eventually, an entirely new language was created with syntax based on Java- and it was also interpreted like Java (as opposed to being compiled and run as machine code).
The jQuery syntax itself is more “human-friendly” and easier to understand. The core of jQuery contains several methods for DOM traversal, while other parts of jQuery contain features for AJAX and animations. jQuery lets you chain multiple functions together for brevity and use shorthand function names.
Comparing The Usage
jQuery’s most prominent use is on the frontend to execute DOM manipulations, i.e. modifying or adding/ removing nodes on the tree. You can also use it for basic animations like movement, transitions, fade effects, etc. And finally, jQuery can make AJAX calls to help update parts of the page with server data without reloading the entire thing.
Comparing The Coding Styles
In my comparison table, I mentioned how jQuery reduces the amount of code you have to write for a given task. That’s because it’s a library maintained by the jQuery team who write scripts for specific actions that you just have to call in your program. It would be like instructing a junior chef in a restaurant on how to make a steak.
The first time, you walk them through each individual step- getting the right cut of meat, seasoning, setting the temperature, searing, etc. But after they’ve done it a few times, you no longer walk them through each step. You just say, “make a steak”, and maybe add a few qualifiers (like the doneness, garnish, etc.).
Comparing The Cross-browser Compatibility
However, there are no guarantees like with all things in programming. And while jQuery supports everything from Firefox to Opera, its latest version doesn’t actively support old browsers. Meaning, that the latest jQuery code isn’t tested and patched for old browsers.
