In application or website development, the front-end UI and backend logic is all that matters. Right? That means getting the right tools for server-side development that make the battle of Node.js vs Go interesting.  

While both Go and Node.js are most favored among the developer community, the question is which one is preeminent for backend development? How do programming languages compare? 

Let's see which one will be more suitable for your project. 

Where is Golang used? 

Go is mostly preferred in applications where the processor is hungry and needs to do multi-threaded tasks. The Golang programming language is more ideal for developing backend applications. 

Where is Node.js used? 

Node.js works more preferably while developing server-side applications as it can handle multiple requests. Moreover, asynchronous architecture in Node.js will build a stable connection with uniting client and server. 

Performance 

In the raw speed criteria, Go is faster than Node.js. Go is directly compiled in machine code as it does not require an interpreter. Due to this, Go performance is considered low-level languages such as C++, while in terms of IO operation, Go is much better than Node.js. In addition, Go and Node.js both have features of the garbage collector. That helps in staving off memory leaks and guarantee stability.  

Node.js is one that was marginally trailing Golang in performance. The single-threaded and much-improved Node.js empower the efficiency and javascript V8 engine make sure that the application runs without requiring the interpreter.   

Judgment: There is very few difference between Node.js and Go in real-life performance. 

Concurrency 

Like worker_thread, Node.js handles concurrency with API. These APIs will make sure that without running bottlenecks, Node.js processes incoming requests.  

On the other hand, Go can handle concurrent tasks. Without making use of much RAM, GoRoutines allow applications to run with multi-threading functions. This makes Go pro in handling and processing- intense tasks without affecting other functions.  

Judgment: Winner is Go. 

Error Handling 

Most developers are more familiar with the Node.js method of error handling. As it uses try-catch exceptions, that error will look instantly while handled at runtime.  

However, God has different ways to check errors during its compilation and runtime. Compilation errors that are frequently syntax related can be rectified in code. Runtime errors need explicit handling so, the return value of the function is required manually inspected. The new version (Go 1.16) can work better on handling with the incorporation of work.   

Judgment: hard to decide 

Tools 

Reducing development time plays a vital role, and reducing time can be possible with ready-to-use tools. In Node.js, developers get 836,000 open source tools and libraries to use via NPM. While there are many tools available in Node.js, choosing one is tough.  

On the other hand, Go does not have more options in the tools, but Go has an authoritative standard library. Tools are limited in the Go. But each tool makes programming simpler. For instance, Test in Go allows developers to run a series of tests in code; however, Go vet filters unsecure constructs.  

Judgment: Node.js have more quantity in tools.  

Community 

Node.js has backbone support such as Microsoft, Intel, and IBM from the Node.js foundation. In 2018 the number of Node.js downloads was around 1 billion. It shows the popularity of Node.js and the support of a community with a wide active size. 

Go has matched it with Node.js popularity in a different way. Go has 83.2k users on Github, while Node.js has 77.6k. So, Go is beating Node.js from a different perspective.  

Judgment: Both technologies have community support in different ways. 

Take Away 

It is really difficult to draw attention to the conclusion of which one is better and who won the battle of Node.js vs Go. Both are worthy in their own nature in building backend applications as Go offers needed computational power, and Node.js works well in asynchronous requests.

So, as per your project requirment you can choose any one of them well, you can Hire Node js developer to built your astonishing node application. Well if you have requirment of generic functionalities for implementing networking and Internet protocols you can also hire Golang developer to buily succesful project
