- It is an open-source, flexible, fast, light-weighted framework.
- It allows cross-compilation.
- It supports interfaces, modules, and classes.
- It is used for both frontend and backend development so that it may run on different devices.
- It allows us to build interfaces that react whenever the user hovers the mouse over them.
- It makes use of limited libraries.
- A single error may destroy the entire website.
- It is a dynamic language so that developers may make big mistakes easily.
- It only supports the single inheritance, not multiple inheritances. Some programs might be required this object-oriented language feature.
What is Node.js?
Node.js was developed and introduced by Ryan Dahl in 2009. Node.js can be used to create a variety of applications, including web apps, real-time chat apps, command-line apps, and REST API servers, among others. However, it is mainly used to build network programs such as web servers. The standard filename extension of Node.js is .js.
Advantages and Disadvantages of Node.js
Various types of advantages and disadvantages of Node.js are as follows:
- js is an MIT-licensed open-source framework.
- It is a lightweight framework that includes minimum modules. Other modules may be included as per the requirement of an application.
- It's a cross-platform framework that works on Windows, MAC, and Linux.
- js applications never buffered any type of data in applications. Node.js applications simply output data in chunks.
- The Node.js library's APIs are all asynchronous or non-blocking. It simply means that a Node.js based server never waits to return data from an API. After calling an API, the server passes on to the next one, and a Node.js notification mechanism assists the server in receiving a response from the previous API call.
- One of the big disadvantages of Node.js is its lack of consistency. The API changes regularly, which increases the developers' problems because they'll have to make changes to their current code base to maintain compatibility.
- It doesn't support multi-threading programming, and it is not with the development of heavy computing applications.
