This is the computer programming language or code that is written to get a web page to perform some type of task. For example it can allow for an interactive map or an animation, or the use of a form.
These are a collection of codes that have already been written that can be used in an application without having to write the code from scratch. Basically, they are a library of codes. They provide the framework in which the project can then be further developed with the specifics that the project is demanding.
There are plenty to choose from, but those that are considered to be the best are the ones that are most commonly used by most of the developers. Following is a list of some examples of these.
This is a single web development framework. It can be used for both desktop or mobile. It has been developed by Google. Originally this was called Angular JS. Why many developers like this particular JS framework is because it has Google support. It has been developed, so it overcomes a lot of the problems that developers were having to deal with when it came to this type of framework. It comes with a lot of benefits such as it makes it easy for developing dynamic lading. It has a lot of great features. Most developers claim that development is much faster with this framework because it has a lot of built in tools. It has easy testing capabilities.
For those who are into heavy web applications they may want to rely on this particular framework. It functions on the RESTful Json interface, which allows for easy connection to the existing APIs. This is a framework that has been around for a long time, so the question is raised as to whether it is still relevant. The answer that most seasoned developers will come back with is yet. It is applicable for older applications as well as newer ones. It is a framework that many developers feel can be trusted for its performance.
For those that want a framework that has additional capabilities, then they will want to look at Node.js. It is a powerful framework that also allows for server side development. It is free, which is an added bonus, and there is the advantage of it working on the most common platforms such as Windows and including Linux, along with some others. This framework can make the claim that it has the largest selection of open source libraries. There is plenty of support information available for those who want to learn to work with this framework.
For those developers that are just starting out, probably the first JS framework they are going to hear about is jQuery. This is because it is one of the most popular among developers. Mostly because of its ease of use and the many different purposes it can serve. It is perfect for animation and event handling. It is easy to work with HTML within the JS framework. Other tools can be utilized with it such as those with React and Angular. As popular as what it is there are still some developers that have a strong dislike for it. Some say that it is no longer relevant and hasn’t been for a long time.
This is provided by Oracle and is not considered to be the easiest to use. What is good about it is that it comes with a lot of documentation. One of the concerns that many developers have when using a new framework is the type of support they are going to get with it. Having good documentation to rely on is a plus.
This is an open source framework, so there is the risk for limited support. However, it has the capability of being able to build elegant applications. It does come with some drawbacks such as ease of use and complexity.
This is another JS framework that is on the popular list. Some of its benefits are that it is simple and easy to understand. The apps are in real time. The downside is that that it is not a great choice for large applications or ones that are considered to be complex.
Overall these are some great choices. What is important is to choose one to learn that seems to have a good future ahead of it. It is disappointing to become proficient with a JS framework only for it to become quickly outdated.
