How do JavaScript frameworks use dependency injection

react, angular, vue: which Javascript framework should you choose?

If you are a little familiar with JavaScript, you may have already made the choice of a front-end framework for your web application. If so, how did you do it?

It is difficult to know all of the frameworks and quickly find out which ones are right for your project.

It is for this reason that we decided to propose an article about three of them the most popular frameworks, in order to review their advantages and disadvantages and specific characteristics.

The choice, relative to your use and goal

Whether you use React, Angular, or Vue, you can achieve your goals and move your project forward.

You need to know how to start and understand the solution you choose to gain proficiency. You can learn from everyone and find certain concepts and principles in everyone else, be it through concepts (API, templating, liaison) or technical implementation.

Namely

Note that performance does not really differ between the different frameworks and is inherent in the use they are made of. It is therefore not a differentiation criterion.

In addition, there is a multitude of documentation on the Internet that will help you understand each framework as best as possible.

However, we'll still see the pros and cons of each to better understand which one to use.

Angular

Angular is certainly one of the most popular and widely used JavaScript frameworks for building front-end applications. While Angular itself isn't new and has been around for a while, the latest version of Angular, Angular 2, is very different from the previous version. In fact, it comes with a host of new tools and new features.

For example, Angular 2 offers ModsDeclarative Els that come with data binding functions. The framework also provides dependency injection as well as unit testing for testing client-side code, making it suitable for all upstream development tasks. It can also be used to develop modern graphics applications.

Finally, Angular is known to offer good flexibility in terms of development.

Advantages of Angular

Angular is one of the most powerful and robust JS frameworks. The frequent updates show the relentless activity of its large community and the adaptability of Angular. In addition to this extremely presented community, the

official documentation is detailed and allows for better understanding. There are therefore more complete models that guide their implementation and offer a range of "off-the-shelf" solutions.

Very popular and complete, especially supports native CSS + HTML, Angular can be found in many companies. Cons of Angular However, be aware that behind these many advantages there are certain disadvantages that need to be considered:
  • Learning Angular is long and tedious, which can be daunting at first, especially during initial development due to the integration of this type of framework.
  • Very complete for web application development, it seems too complex especially in his code. Make sure that you do not get lost in view of the many solutions offered (experience as the best associate).
  • Some Migration problems may have occurred during the transition from old to new versions. While version updates are bound to resolve these issues, the complexity of Angular can cause problems with the same updates.

ReactJS

Respond to what we call ReactJS is a free JavaScript library created by Facebook in 2013.

It enables web applications to be designed by creating dependent components of a status that is an HTML part for each status change.

This is a framework recommended by companies that provide JavaScript development solutions. It is an easy-to-use web development framework. React can be used to create a front-end user interface and provides a template that is suitable for all web developers.

Did you know?

ReactJs only supports the interface of a web application and can therefore be used with an MVC framework such as Angular.

Benefits of ReactJS

The main advantage of React is that it can help develop a component that will be reused over and over again. This simplifies the web development process considerably.

When developers work with a group of elements with different data, the only way to reuse components created with React is to implement a range of different data. This makes it one of the best Java frameworks and makes React one of the most popular tools.

ReactJS is used by many startup companies, including Netflix and Airbnb, to name just a few.

Since React is 100% OpenSource, it is constantly updated and adapts to the limitations of development, which evolve over time.

WithReact, creation is simplified thanks to its flexibility and its API, which make it easy to use the components. Also note that ReactJS works with a virtual DOM, which can increase performance and speed.

Disadvantages of ReactJS

Before these various advantages, there are some disadvantages:

  • TheModels of the components are in JSXand not in HTML, which requires minor customization (although we are still pretty close to HTML).
  • Despite the elements that are present in the web to help you, there is oneLack of "official" documentation to ReactJS that doesn't make it easier to understand when you are a neophyte. ReactJS requires practice, especially for integration into the MVC framework (despite the ease of use).
  • React offers developers A large selection . What can be perceived as quality is also a mistake, since it does not make a clear decision and leaves it to the developer to decide. Not always the most comfortable.
VueJS

VueJS is our third JavaScript framework of the day. It was created in 2013 and introduced in 2014 and is the easiest to understand.

Advantages of VueJS

One of the great advantages of VueJS is its simplicity given the reduced choice of options (as opposed to a ReactJS for example). It adapts to your skills, whether you are a beginner or advanced in front-end development, and allows you to get into the world of JS frameworks as easily as possible. Associated with this, you will find clear and complete

who accompanies you.

Finally, note that it's HTML and CSS compatible: so you don't have to adapt to a new language (and neither do you), which saves a lot of time.

Disadvantages of VueJS

In the disadvantages of VueJS we can quote:

  • Be

(mainly due to the fact that it is the youngest of the three frameworks). Here is a first approach to three major JavaScript frameworks. Here we wanted to get you into this universe, sometimes a little nebulous, all by offering interesting content for non-beginners (which seems pretty "basic" to advanced learners).

This article is not exhaustive and, above all, is constantly being developed. It is meant to be a clarification that will enable you to consolidate your choices of front-end framework, although there are different ones

There are JavaScript frameworks that you can examine. It's up to you to test and give us feedback in the comments.
