In addition, since version 6 of Java, a completely different programming language and alien to JS, includes a package (javax.script) which enables the integration of these two languages through an API capable of creating scripts to improve the runtime performance of certain Java applications.
These are nothing more than those applications that need to have the browser integrated within its infrastructure in order to run. This is known as webview mode which is a navigation interface with no other option than the visualization of the pages of the hybrid app. Therefore these apps are created using all available web technologies (HTML + CSS + JS) and are executed as if they were web pages.
As you might expect native applications do not run in webview mode, in other words these apps are not a conglomerate of web pages but are fully debugged and compiled applications, just like those developed with other contextual languages.
So, having clear the types of applications that we can create with JS and that thanks to certain runtime environments such as Node.js or AngularJS this language turns out to be a powerful development alternative capable of producing applications that meet market standards, it is time to point out its advantages and disadvantages in every sense.
● Simplicity: Compared to such a popular language as C++, writing code in JS is noticeably simpler because its syntax is Java-inspired.
● Interoperability: JS can be implemented in all types of applications thanks to its support for other programming languages such as PHP.
● Server load: Its demand for server resources is low and, in some cases, null.
● Robust interfaces: FrontEnd development with JS provides better user interfaces (UI) and also enhances the user experience (UX).
● XMLHttpRequest: Designed by Microsoft in JS this object is invoked as an HTTP request which creates asynchrony on the server to send and receive data on both sides without reloading the pages.
● Global acceptance: Many of the most important companies in the world believe in this language, that is the case of Google and Facebook who created AngularJS and React.js respectively.
● Performance: By reducing the length of the JS source code, it improves performance in the delivery of websites and applications.
● Extended functionality: Thanks to plugins created by third party developers can integrate predefined code snippets to create applications more easily and quickly which translates into saving time and money.
● Security: Since all users are able to see the JS code of the sites, others can use it maliciously.
● Compatibility: JS code must be tested on many platforms before being published because some may not support its latest features.
● Resources: In some cases there may be a situation where there is no support for the latest API and reverse engineering is needed to implement them.
