Paper Example on Angular and React JavaScript Frameworks

Introduction

JavaScript frameworks are developing faster in the modern days such that there are frequently updated versions of Angular, ReactJS and other players in the market such as Vue.js. Angular and ReactJS have been known to be the top two best JavaScript frameworks that individuals can use in their application.

Angular is a JavaScript framework that is for the development of web applications. Google has done the creation and maintenance of Angular, and many Google services such as Google AdWords and Google AdSense make use of Angular for the development and support of the interfaces they use. Results as per the StackOverflow survey rated Angular as one of the popular front-end development frameworks. The front-end system is also on constant evolvement, and it changes on a daily basis. The significant development of tools lead to them becoming bestsellers in web app development, revolutionization of the workflow and others continue to grow dead-end. ReactJS has also had an excellent rating since it was also known to win popular affections (Pano et al. 2016). The developer community and Facebook today maintain ReactJS. Majority of the leading companies such as Apple, PayPal and Netflix make use of the JavaScript framework and other websites get built through its use.

The most straightforward version of Angular to use is Angular 5 because it is faster and lighter compared to former versions. Angular 5 is rather sizeable when it is close to other frameworks of web development that tend to make it suitable for building applications that are large and enterprise-sized when complex components are involved (Jain, et al. 2015). Angular 5 contains the build optimizer function that is enabled by default. The use of the build optimizer is that it removes the code that appears necessarily during runtime hence making the bundles created smaller. The method of using fewer systems is to mean that the application will run faster. The removal of Angular decorators is intended to achieve build optimization.

Angular 5 has TypeScript as well as improved compilation because it uses TypeScript language even though it belongs to JavaScript (Freeman, 2017). The advantage of using TypeScript is central because of the typed nature. With the use of JavaScript, one may discover errors that they make during the creation of codes only during runtime because they tend to be easily overlooked when having the code written. However, the use of TypeScript is efficient because it detects any errors as individual types hence making it easier for them to correct immediately. The improved compilation is achieved where Angular 5 comes with TypeScript 2.3 making compilation faster compared to the previous versions, and the compiler supports incremental compendium as well.

Angular 5 simplifies the creation of following web application. Angular 5 has the feature of enhanced possibilities for progressive web applications which are the web applications that appear to the user the same way as native mobile applications but the difference between the two is that the progressive webs are created for running in a browser while the native ones are designed for particular devices (Hevery, & Abrons, 2009). The popularity with PWAs is for the flexible compatibility with other devices as well as its responsiveness and that there is no need to publish in an Appstore which is crucial for app development. Angular 5 is used as a tool for more natural creation of web applications and also offering native experiences.

Angular 5 also uses a web pack which makes it a convenient and useful tool. Webpack is used to refer to the module bundler that joins the assets which belong together, and that should be returned together by the server using a single JavaScript file (De Sanctis, 2017). Thus, web pack is known to be an excellent bundling tool for most applications that are large and complex with the use of assets of various types. The features mentioned above about Angular 5 are the main reasons why one should use it for their projects, and it is the reason for its rating as a top framework. Angular development is more consistent and efficient with the use of Angular 5 because it is the most optimal choice for projects that are for creating feature-rich single-page web applications.

ReactJS is also beneficial, and its advantages have led to its top ranking as it is excellent for building large web applications where data can be changed on a regular basis. React JS contains JSX that facilitates the overall process of writing components (Klementowski et al. 2017). The JSX is a syntax extension to JavaScript that is effective in making the writing of one's elements easier. JSX accepts HTML quoting, and it also makes it easier for subcomponent rendering. It uses a set of shortcuts to arrive at great writing components with the use of a few rules that make the source cleaner and more straightforward (Lemke, 2018). JSX is useful when it comes to building apps of high-volume or other custom components with the exclusion of typos in structures of large trees, and it also makes the conversion easier. The React developers are also provided with informative warning and error messages that help to prevent the injection of codes.

The use of supplemented React, a feature of ReactJS which can reuse system components helps to boost its productivity and also facilitate further maintenance (Aggarwal, 2018). Most times, updates become a nuisance because applications have complex logic and change into one component thus affecting others and Facebook came up with the supplemented React to solve the issue. Facebook also developed the Virtual DOM (document object model) that ensures faster rendering. When building an application of high load, it is essential to consider the structure and its impacts on the overall performance of the app (Archer, 2015). Virtual DOM is a solution to the use of React in heavy loaded and dynamic software. DOM is a virtual representation in that all the changes go through DOM first then necessary operations of DOM are calculated using diff logarithm and minimal scope. There are also updates to the real DOM tree that ensure that only minimum time is consumed and this makes the method provide higher performance of the app compared to other versions (Mariano, 2017). There is a stable code guaranteed where ReactJS uses only downward data flow.

Conclusion

For a real engineer, there is no substantial difference when it comes to the frameworks to use as they can always modify to come up with better versions to suit their operations. Additionally, it takes some time for them to get used to the new one in the market. ReactJS and Angular 5 have been rated excellently for their broad applications in web development, and thus companies show grow expertise in these fields. However, there are also cons of the framework which means that there needs to be the right choice for each case during the development of products.
