In application and software development, there are a few cases where all code is created by hand, and in most cases, frameworks and libraries are used.
In this article, you will learn what React.js is and what can be done with it, why you should learn React.js and its advantages.
Not only engineers who actually want to learn and develop React.js but also people in charge of companies involved in application development can understand it gently.
As introduced in the overview section, React.js is an open-source library, so there is no cost to implement it. Since the official site has a lot of startup guides and tutorials, it is also possible to build an environment from scratch according to the preferences of engineers.
Another easy way to introduce React.js is to use an environment construction tool (also called a toolchain) and react training kolkata. For example, there are quite a few tools that easily prepare a React.js development environment, such as "Create React App", provided by Facebook. Depending on the device and environment used, there are cases where the tool cannot be used, but it is good to remember it as one of the introduction methods.
In a nutshell, the feature of React.js is "a library for building UI (user interface)".
React.js includes screens for users to use web services (sites) and applications, as well as code useful for creating UI. The track record of being adopted by famous SNS and web services such as Facebook and Instagram is a sign of the usefulness of React.js. Despite its popularity, React.js is an open-source library that is constantly being updated. If you are aware of the advantages of learning React.js, react js course with placement will be a good option for you.
The official site lists three features of React.js.
In the following, you will learn these three characteristics in detail.
Declarative means "you don't have to do a whole change for a partial update". By taking a declarative approach, React.js can understand when data changes and efficiently update only the relevant elements (components).
A component is a building block. React.js creates its components and combines them to create an interface. It is open source, can be used by anyone, and is very popular with engineers. In short, the ease of customization is attractive.
By learning React.js, you will be able to use the framework "React Native", which is also used for Smartphone application development. The point is that even if you want to add a new function to something that has already been created, there is no need to rewrite the existing source code, and you can use it as it is.
Easy to maintain high speed, good performance
React.js works with virtual DOM (Virtual Document Object Model). With this virtual DOM, only the parts that are different compared to the actual DOM are reapplied to the HTML. In other words, it is a very speedy mechanism in that only the parts that need to be updated are applied.
Low learning cost and easy for engineers to learn
There is a future
Of course, creating your own learning environment and increasing the number of engineers who can use React.js is also a good option. It will also lead to the accumulation of know-how in-house, and the range of future development environments will expand.
However, as long as you don't have the know-how at the moment, it's more efficient to ask a professional in the field to develop a React.js system on your own.
Even if you can't get your own engineers to learn right away, there are already a number of companies that are confident in their development, so you can outsource and run them in parallel. Please choose the best method from various options.
