JS allows you to develop and integrate animation, multimedia, and any other updated content on any platform. With its help, interactive pages for websites are developed, and games and applications are processed.
Advantages and Disadvantages of JS
Compatible with various programming languages.
Applicable to the development of both external and internal interfaces.
Suitable for creating products of varying complexity.
Forms an open-source platform.
Is an indispensable technology for the development of websites and applications.
Despite its many unique features, the language has its disadvantages:
One mistake is enough for the entire platform to stop functioning.
Due to the availability of the language, there is a high probability of a security threat.
Does not support remote access, so it cannot be used for network applications.
Does not have strict typing and interpretation rules.
Sometimes it is not possible to quickly and timely find a code error, especially in the early stages.
To provide at least some security, there is no support for reading and downloading files on the client-side.
Advantages and Disadvantages of Node.js
The main advantages of Node.js:
Has asynchrony, which is suitable for the simultaneous execution of several tasks at once.
Opens access to the system for several users at once.
Has an open-source code that opens up unlimited possibilities for work.
Provides high scalability, thanks to the event mechanism.
Does not buffer data.
Provides sufficiently high performance and speed.
Is a cross-platform framework that runs on Windows, MAC, and Linux.
Has a high speed of work, thanks to the Google Chrome V8 engine.
But due to several shortcomings, Node.js can't handle absolutely everything:
Unable to cope with heavy computational tasks.
Thanks to asynchrony, it uses callbacks, which often complicates the program and the code itself.
The constant need to make edits to keep up with the frequently updated API.
Node.js provides a more flexible development process, so without it, working with JS will be very limited and take an order of magnitude longer.
There are many differences between JS and Node.js:
JS can run on multiple engines, making coding fast and easy. You can also put the application in any working environment. Node.js only runs on the V8 engine (Google Chrome). But due to the possibilities of JS, this problem does not lead to limitations.
A large number of well-known projects around the world use Node.JS and JS. This fact speaks for itself. Technology deserves attention. And we have compiled a list of the TOP 3 companies that choose Node.JS and JS.
