Pro & Cons of Node.JS and Golang Which One best Web Developer to Choose

In the modern-day world, Web Development is not a thing from the past. You can quickly learn and manage web applications using basic languages such as python, Golang, and Node.js. Businesses always want an advantage over other businesses in the same field. They get their websites, and web applications or native apps developed faster and with fewer expenses.

With advancements in technology, the coming programming languages are proven to provide an intuitive web and seamless user experience. The increase in technology has demanded the emergence of new programming languages for better website functionality, such as Golang and Node.js.

Node.js is a language which is built on the server side of Chrome’s Javascript. It was developed for making web network applications fast and in an efficient manner. Node.js uses an I/O model, which helps in making Node.js a lightweight, feature-rich language. The I/O model helps in handling extensive data from various sets of applications. Node.js applications are run in JavaScript, and most of the code can be run in run time on OS X, Windows, or Linux.

In short, Node.js = Runtime Environment + JavaScript Library.

Features of Node.js,

1- Node.js uses a single-threaded system. It means that the machine helps the server never to block call requests and generates responses on a priority-based task. It just uses a single program, and that single program can provide service to a large number of requests.

2- Node.js is very fast in execution since it was built on Google‘s V8 JavaScript Engine.

3- Node.js applications never buffer any data. These applications simply output the data in chunks.

Disadvantages of Node.js,

1- If you are running high computing tasks, then node.js is sure to perform at a lower level and reduces performance.

2- The frequent changes in the API of Node.js made the developers undergo a good amount of heavy changes in their app.

3-The lack of library support can endanger their code.


Go is an open-source programming language that makes it easy enough to build simple, reliable, and efficient software in no time. This tiny-looking language can provide the greatest of the features which most languages will fail to deliver. The golang was first released in 2009 by a team of workers working in Google.

Advantages of golang are,

1- Golang takes less efforts to make an app, whether you are talking about financial efforts or physical efforts.

2- Golang is a flexible language that can solve a lot of problems in less time. Golang can be used for system and networking programming, making apps, machine learning, audio and video editing, and much more.

3- Just like C, C++, Go is also a language that lacks an interpreter. This cannot be taken as an advantage because this will take less time to execute and run than other languages, which used to take a lot of time.

4- Golang can run in minimum system requirements as well, so any app made in golang will require fewer system requirements and hence will be able to be used by more and more audiences.

Golang vs. Node.js Which is the better bet?

We gave you a piece of brief information about what are golang and Node.js. Now let’s compare both based on certain examples,

1- Performance:

The performance of an app greatly affects the application loading time and its performance over time. Since Golang is based a little bit on C and C++, so the performance of Golang is excellent. Since golang lacks a virtual machine and it is directly compiling everything to machine code, so the programs are executed at much faster as compared to other apps.

On the other hand, Node.js is considered the best backend language to work around for several reasons,

  • Node.js uses the V8 engine to compile the code. The V8 engine is the fastest engine till now available.
  • The code of Node.js is reusable, which means that the applications you are using, such as any social media application. With the help of code reusability, the apps can get themself updated on the server in real-time.

In terms of raw data, Golang can perform well, but considering the performance in demand, both golang and Node.js serve the exact result.

2- Concurrency:

Concurrency is any method by which the process of execution of apps is divided into multiple streams, which are later executed all at once in a flow. Concurrency of an application basically makes sure how an application can handle many of the requests from the server-side or the client-side. The more concurrent an app is, the better he will be able to handle the workload.

The creator of the golang told in the documentation that in times of large server requests, you can switch the process to goroutines which can handle the load in an easy yet efficient manner.

Compared to Node.js, which is a single-threaded language resulting in slow applications that cannot handle the server load or the client-side requests load inefficient time and manner.

3- Tools

Node.js has a large variety of tools to make the work for developers less demanding and more efficient. On the other side, GOlang has tools but lacks the most important ones, resulting in more time for solving server-side issues.

It is quite hard to say which language is the best, it greatly depends on the nature and the requirements of the app you are creating. Each task or app requires different tools, and both GOlang and Node.js are extremely good at it. While GOlang is perfect for micro-services and enterprise-scale projects. Node.js, at the same time, is best suited for projects that require ready-made solutions for almost every development process.
