Comparative study

During the last couple of years, JavaScript has become the foundation for a quickly evolving landscape of libraries and frameworks. With the consistent emergence of fresh and innovative tools, it can be a daunting task for developers to take their pick from various technologies.

Both jQuery and AngularJS are two of the leading topics of the present day web development field. So, how can you differentiate between them? What are the key features they support? And as a developer, which one should you choose? Through the course of this post, we’re going to go over a small comparative study between jQuery and AngularJS.

jQuery

jQuery is a JavaScript library that lets developers write less and do more. Put simply, it offers a very efficient and mature way of accessing, querying and modifying elements in DOM (Document Objective Model) and simplifies things like animation, event handling, and Ajax. In addition, jQuery offers an extensive repository of plugins developed by its large community. It takes the complex coding involved in manipulating the DOM and transforms it into a simple solution that can be used by developers to make modifications with single lines of JavaScript.

The key technical features that every developer should be aware of when using jQuery include:

CSS manipulation solutions

HTML and DOM manipulation frameworks

Event handling strategies

JSONP / Ajax

Cross-browser compatibility

Animations and effects

Lightweight

AngularJS

AngularJS is a kind of open-source JavaScript framework designed to aid developers to create their SPAs according to best practice solutions for web development. With AngularJS, the risk of producing damaged code may sometimes be limited as a more structured space to develop SPAs is offered. Key technical features offered by AngularJS include:

Angular directives

Templating features

Dependency injection features

Two-way data binding solutions

Form validation

REST API

MVC support options

Which one should you choose?

Some developers may suggest that AngularJS and jQuery aren’t comparable because they significantly differ from each other as one is a library while the other is a framework. However, a brief comparison can be done keeping in mind that these are the two most prominently used JavaScript toolsets of the present day.

Dependency injection: jQuery hasn’t made it a necessity. You can usually access your plugins without any problem as long as you don’t have the scripts called as anonymous. In a project, dependency injection is mainly used for modularity. It’s all about keeping the functions local so they run in a controlled environment. On the other hand, AngularJS uses heavy Dependency Injection. You need to inject everything about AngularJS.

Animation support: Both jQuery and AngularJS allow the use of animation. While jQuery offers direct access to .animate() function, an additional library (ngAnimate) is required in AngularJS.

Two-way data-binding: It allows for direct modification of the on-screen HTML and DOM as a user types and interacts with your website. With AngularJS, it’s built in directly, whereas you need to write JavaScript to attain this in jQuery.

Form validation: This is one of those advantages that you can enjoy with AngularJS. Adding a form element into a page gives you access to various functions in the DOM. On the other hand, jQuery doesn’t offer this feature. You can use a third-party plugin like the jQuery Validation Plugin or write them yourself.

jQuery is a simple library of code that’s been specifically designed to help developers manipulate DOM with JavaScript. Whether it involves contributing your pre-existing framework with a fresh jQuery plugin or designing a website from-scratch alongside an array of vanilla JavaScript, it’ll depend on the specific requirements of your project.

On the other hand, AngularJS is the perfect solution for developers to use when they wish to create powerful and robust applications from scratch. AngularJS provides developers with the tools they need to create the client side of applications.

While both of these offer a decent amount of functionality if you’re looking to develop robust applications, use AngularJS. Or else, stick with jQuery that lets you develop a flexible website. It also lets you easily manipulate the DOM – which is one of the most common processes in the web development landscape. So, it seems to be a better option for developers to use jQuery as long as present day’s rapid as well as fast development process is concerned.

Security issues with jQuery

These days, it’s almost impossible not to utilize one of the thousands of JavaScript libraries available when it comes to developing in JavaScript. Libraries make coding more efficient and simpler by taking processes, which would usually need several lines of code to accomplish and simplify them.

Let’s have a quick look at the common security vulnerabilities.

Cross-site request forgery: It enables hackers to utilize a user’s browser to take actions on other websites.

Buffer overflows: It happens when cybercriminals send data which is too large for the buffer to hold. It leads to data being written outside of the buffer and lets hackers crash an application, corrupt data, or insert malicious code.

Cross-site scripting: It enables hackers to inject harmful code into trusted websites that then serve the malicious code to users who browse the site.

The solution

When it comes to mitigating security risks associated with open-source projects. Open-source VPN clients are usually considered to be the most secure solutions available as they’ve their source code on display for everyone to see, inspect and audit. However, it’s important to note that unless you’re ready to go down the manual setup, you’ll need to sign up for a reliable VPN provider here at VPNpro you can take a moment to figure it out which VPN provider may be the best option for you.
