Golang Vs Node JS 2020 -Crucial Features Compared

 Golang and Node.js, both are the growing technologies used for back-end programming. While Golang is an open-source programming language, Node.js is an open-source server framework.

Do you know the secret behind the success of apps like Facebook, Instagram, Whatsapp?

If you are guessing the concept, the idea, the hype, the app, the UI/UX of the app are a show stopper, well, you are somewhere close.

Apart from these things, the backend force that drives these aspects is the real show stopper of the applications.

A solid backend guarantees app performance and scalability and ensures security. Backed errors are the reason you may experience app crashes under high loads, long response times, and even data leaks.

What is Golang?

Golang, or Go, as many refer to it, is an open-source programming language developed by Google. Introduced to the developer community in 2009, Go is a statically typed, multipurpose, cross-platform, and high-performing programming language.

Go was set to combine the advantages of the most popular languages while eliminating their drawbacks. The language is quite similar to C in terms of speed and syntax, which allows for writing readable and maintainable code. On top of that, Go is as efficient as C++ and Java.

Go is now utilized by companies such as Uber, SoundCloud, BBC, Basecamp, and others.

What is Nodejs?

Introduced in 2009 and built on Google Chrome’s V8, Nodejs written in JavaScript is an open-source, server-side runtime environment. It is one of the most preferred choices by developers when it comes to cross-platform app development. Also, be an event-driven, non-blocking I/O model design, it is most recommended to develop highly scalable server-side applications.

When it comes to why use node js, the answer is- it becomes easier for app developers to write both server-side and client-side scripts all by using a single language. Furthermore, support from Linux, Unix, Windows, Mac is filled with open-source JS libraries meant for simplifying web application development using Nodejs.

Node.Js vs Golang — Who is the winner?


One of the objectives Go’s engineers prevailing in was to accomplish a superior execution. In general, Go is exceptionally light-weighted and quicker when contrasted with Node.js.

Its exhibition qualities are fundamentally the same as those of C/C++, which are excellent.

In the meantime, powerfully composed Node.js depends on a deciphered language, which by and large renders slower than most of the incorporated dialects.

It doesn’t achieve crude execution of CPU or memory bound errands, in spite of Go. Hub execution can be either high or awful, depending on what application you are chipping away at.

All things considered, such examination is reasonable as far as crude execution. While, in actuality, execution the two innovations can exhibit almost similar outcomes, the general server execution is influenced by various different variables.

For example, when system correspondence or database association is included, the exhibitions of Node.js and Go are frequently equivalent, and they work at comparable paces.

Concurrency and Memory Management

Node.js is single-threaded, which indeed helps it managing load balancing on server side for subsequent requests coming from multiple users but it is not a multi threaded language. Node.js does not possess capability of pointers for better memory management.

While Golang is multi-threaded by using its inbuilt capability of goroutine/s and hence support concurrency to a great extent. Developers can implement goroutines while writing function/s. Go also has a concept of pointers what it has inherited from “C” but not completely. Go does not support arithmetic operations on pointers.

Handling Errors

These technologies use different mechanisms of error tracking. Node.js provides a traditional and popular with developers way of error handling, called throw-catch. It means that errors are shown and require fixing before developers move to the next stage.

Go uses several ways of error handling for different kinds of errors; for example, for compile-time and runtime errors, which leads to confusion. Golang developers try to simplify this process with new releases.

For this reason, Node.js gets the point: its throw-catch approach is more precise and well-known among developers.


After comparing Golang vs Node.js from different points of view, it is quite difficult to choose between the two. The choice of selection is totally dependent on the type and features of the application you want to create. In our view, both Go and Node.js are good at different things.

Our verdict is- Golang seems to be more promising than Node.js because it’s a programming language in itself and offers certain features what do not support by Node.js. Though Node.js has great options for almost every kind of development challenge, Go still is capable to handle a very high load of work & enterprise-scale projects.

Native vs Hybrid app - What to Choose?

Mobile applications are regarded as one of the most powerful business tools in the industry. They have become the new standard for connecting with customers. As mobile app development times keep getting shorter and time to market becomes increasingly important, a highly debated question before any mobile app development team is whether to build applications that are directly written on native platforms or use React Native, Flutter, etc. to build hybrid apps. Hybrid apps use native code in conjunction with web languages to gain a set of unique attributes while taking considerably shorter times to develop. At the same time, native apps, more often than not, provide the best user experience. Your mind must be racing with a question, which one between native vs hybrid development can be the right choice for your business. Let’s get into the nitty-gritty of native and hybrid app development approach, know the pros and cons, and settle this question once and for all. Native iOS applications

Why SaaS (Software as a Service) is good for your business?

Software as a Service is considered as the most thriving branch on the IT market. Analysts from Forrester Research estimated the average market value growth at 56.2% annually and forecast that it will continue to burgeon by 2020 at a speed of 18.9% per year. It comes as no surprise that the SaaS market is expanding rapidly. This type of business model has plenty of advantages that attract new entrepreneurs to follow the very software distribution model. On the other hand, companies are more willingly to choose SaaS over on-premises apps, as it is more beneficial and secure solution. Let’s Discuss the 5 Solid Reasons why SaaS ? Speed to market Traditional software required extensive planning and lengthy project management to deploy. Change management programs were created, transition phases planned, transformation programs developed, risk mitigation plans devised and user acceptance tests implemented. Deployments could take weeks, months or even years. SaaS enables businesses to pass ow
