Golang vs Node.js

Node.js is a wildly popular option for creating backend apps. Go is quickly increasing in popularity as a general web dev language. Which do you prefer?

Node.js vs Golang has been the theme of many internet wars. Going by the numbers, the end to this debate seems nowhere in sight. However, we decided to take the plunge and do a bit of research on it. To come up with a more accurate verdict on Node.js vs Golang, we read up a bit on it. So here goes.

No search on the internet can begin without a search on Quora. Here’s what we found; it points to how developers see Golang as an excellent replacement choice for Node.js. We have a completely unbiased view on this! Let’s try and make sense of what is happening and why developers, as well as businesses, are starting to choose Golang over the popular Node.js.

Node.js Performance:

Firstly, anyone who has used both the languages would realize that CPU performance or memory bound tasks are slow with Node.js. Node.js is based on JavaScript, an interpreted language. Interpreted languages are slower than most compiled languages. With Node's dynamically typed nature, it does not reach the raw performance that Go can achieve. In contrast, Golang’s performance is similar to C or C++(C is another compiled language). Only in cases of network communication or database interaction can Node equal Go in performance.

Concurrent and Scalable:

This is another aspect in Go vs Node where Golang beats most of the modern computing languages. Node is no exception to this rule. Golang is scalable due to its “goroutines.” Goroutines help multiple threads perform simultaneously. Also, execution of parallel tasks is efficient and reliable. As Node.js is single-threaded, instructions are executed in sequence. This limits its ability during massive scaling when a lot of parallel processes are executed at the same time.

Language Maturity:

Any comparison between the two languages would also be incomplete without a look at maturity. Golang is quite robust and mature for its age, while for Node the changing API becomes a cause for API problems for developers who are writing and using Node modules.

To be fair to both the languages, it is not as though Node.js is going out of “business” anytime soon, but, when it comes to developing “business” solutions, Golang is the best choice. Golang's performance is lightning fast, its goroutines allow for great scalability and concurrency, and it helps build way more robust applications. When you consider Node.js vs Golang, Golang is the wiser choice. Thus the verdict is out on Go vs Node.
