Why is Nodejs better than Other Languages?

Why NodeJs, and what distinguishes Node from other programming languages?

Introduction

The definition of Node js is quite complex. Node js is a not programming language nor is it a framework or a library. On their official website, Node.js is defined as a JavaScript runtime built on Chrome’s V8 JavaScript engine.

Node.js is a programming language that may be referred to as a technology. It is mostly used for backend operations and is/can be used in conjunction with front-end JavaScript frameworks such as Angular, React, and Vue. The design of Node.js is comparable to Ruby’s Event Machine and Python’s Twisted.

Benefits of Node.js over other technology?

Aside from being effective at what it does, Node.js is popular because it has a huge, active, open-source, JavaScript-based ecosystem. Also, it doesn’t tend to break compatibility between versions in major ways.

  • The scalability provided.
  • Node.js is light and fast.
  • Many hosting providers are available.
  • Highly extensible.
  • Its caching ability.
  • Node.js is simple to learn.

How Does It Work?

nodejs architecture

Node.js is the JavaScript runtime environment that is based on Google’s V8 Engine.

i.e. with the help of Node.js, we can run the JavaScript outside of the browser.

Another thing that you may or may not have read about Node.js is that it is single-threaded.

Based on event-driven architecture, and non-blocking based on the I/O model.

Why is Node.js so popular?

V8 is a set of libraries built on top of an extremely powerful virtual machine.

Node.js is a bundled version of Google’s V8 JavaScript engine, the libuv platform abstraction layer, and a core library written mostly in JavaScript.” It’s also worth noting that Ryan Dahl, the Node.js founder, was attempting to create real-time websites with push functionality. He provides developers a tool to work in the non-blocking, event-driven I/O paradigm with Node.js.

Event-driven asynchronous callbacks.

To understand why Node.js applications have to be written this way, we need to understand how Node.js executes code. Node’s approach isn’t unique, but the underlying execution model is different from runtime environments like Python, Ruby, PHP, or Java.

NPM: The Node Package Manager

The idea of NPM modules is quite similar to that of Ruby Gems: a set of publicly available, reusable components, available through easy installation via an online repository, with version and dependency management.

A full list of packaged modules can be found on the NPM website https://npmjs.org/ or accessed using the NPM CLI tool that automatically gets installed with Node.js. The module ecosystem is open to all, and anyone can publish their module that will be listed in the NPM repository.

Some of the most popular NPM modules today are:

  • express – Express.js, a Sinatra-inspired web development framework for Node.js, and the de-facto standard for the majority of Node.js benefits out there today.
  • socket.io and sockjs – Server-side component of the two most common websockets components out there today.
  • Jade – One of the popular templating engines, inspired by HAML, a default in Express.js.
  • mongo and mongojs – MongoDB wrappers to provide the API for MongoDB object databases in Node.js.
  • Redis – Redis client library.
  • coffee-script – CoffeeScript compiler that allows developers to write their Node.js programs using Coffee.

Where Node.js Can Be Used?

  • Server-side programming
  • Mobile App Development
  • Back-end API services
  • Web application

Analyzing Node.js vs other programming languages

Of course, there are lots of different languages out there to choose from, and each one will bring something different to your project or application. To help you decide, we’ve put together a comparison of Node.js and some of the main alternatives available.

Node.js vs Python

Python is an object-oriented, high-level, interpreted programming language with a focus on readability and productivity. It was founded in 1991 and supports a number of programming paradigms, making it an excellent solution for a wide range of commercial operations. As a result, it is simple to use and create, with a large standard library and environment.

This makes Python perfect for CPU-intensive apps, which, as we’ve seen, aren’t a strong suit for Node.js. Python also has the upper hand when it comes to time-sensitive development and deployment options. You won’t need to look for numerous utility modules and packages for your application because it comes with a vast standard library and modules.

Instead, you can start working on the project right now.

In addition, Node’s power in handling heavy I/O operations and shuffling of data between the front end and the back end makes it the better choice for Single Page Applications and Real-Time Applications.

Node.js vs Java

Web apps, mobile apps, real-time applications (instant messaging, live chat), online gaming apps, e-commerce transaction software, and more can all benefit from Node.js.

It’s also a smart choice if you’re working with microservice architecture, which can serve as the foundation for more complex systems – remember, Node.js was used to create apps like Netflix and Uber.

Java, on the other hand, is ideal for CPU-intensive or CPU-bound applications. The same is true for programs with a large codebase: because Java uses tightly typed sources, refactoring and bug fixing will be easier during maintenance.

Java is a wonderful choice if your application employs an RDBMS (Relational Database Management System) since it offers capabilities that facilitate multi-database object-relational mapping.

Nodejs vs Other Technology Architecture?

Pros of Nodejs:

If your application doesn’t have any CPU-intensive computation, you can build it in Javascript top-to-bottom, even down to the database level if you use JSON storage Object DB like MongoDB.

This eases development (including hiring) significantly.

Crawlers get a fully rendered HTML response, which is considerably more SEO-friendly than, say, a Single Page Application or a Node. js-based websockets app.

Cons of Nodejs:

Any CPU-intensive computation will block Node.js, therefore using a threaded platform is preferable. Alternatively, you may scale the computation out.

Using Node.js with a relational database is still quite a pain (see below for more detail).

Pick up any other environment, such as Rails, Django, Python., or Java MVC if you want to try to perform relational operations.

In Conclusion:

We already know that Node.js and other languages such as Python and Java have advantages and disadvantages and that they are utilized for various types of projects.

So, when deciding between Node.js and other languages like Python, Java, weigh.

All of the benefits and drawbacks to choosing which is ideal for your project application.
