? Picking between Go and TypeScript for your backend? Let's take a look at each language to see which suits your project best.
| Feature | Go | TypeScript |
|---|---|---|
| Performance | Fast | Depends on the framework/runtime |
| Learning Curve | Simple to learn, can be difficult to master | Easy for JS devs, some nuanced complexities |
| Concurrency | Built-in (goroutines) | Depends on the runtime |
| Type System | Static, simpler | Static, more dynamic |
| Ecosystem | Growing | Vast (npm) |
| Use Cases | Microservices, systems programming | Large web apps, full-stack JS |
Let's dive into what makes Go and TypeScript tick when it comes to backend development.
Generally speaking, Go is focused on simplicity and speed, while TypeScript's built for versatility and adding type-safety in the JavaScript world. Let’s look at how these two type systems stack up against each other, with a few code examples along the way to keep things clear.
Both Go and TypeScript are statically typed languages. But they take different approaches to keep your code in check.
// Go example
func greet(name string) string {
return "Hello, " + name
}
func main() {
greet(123) // Boom! Compilation error: can't use an int as a string
}
// TypeScript example
function greet(name: string): string {
return "Hello, " + name;
}
greet(123); // Nope! Error: number is not assignable to type string
How much do you really have to spell out for the compiler? Let’s see how these languages handle inference.
// Go inference example
func main() {
age := 30 // inferred as int
var name = "Alice" // inferred as string
}
// TypeScript inference example const age = 30; // inferred as number const name = "Alice"; // inferred as string
Generics are all about creating code that’s flexible enough to work with any type. Here’s how each language handles them.
// Go generics example
func Print[T any](value T) {
fmt.Println(value)
}
func main() {
Print(123)
Print("Hello")
}
// TypeScript generics example
function print<T>(value: T): void {
console.log(value);
}
print(123);
print("Hello");
Takeaway: TypeScript’s generics are more advanced, letting you customize and control types. Go’s approach is simpler and gets the job done without the frills.
Let’s talk about data structures and how these languages let you organize types.
// Go example
func greet(name string) string {
return "Hello, " + name
}
func main() {
greet(123) // Boom! Compilation error: can't use an int as a string
}
// TypeScript example
function greet(name: string): string {
return "Hello, " + name;
}
greet(123); // Nope! Error: number is not assignable to type string
Takeaway: Both languages use structural typing, but TypeScript’s interfaces are more versatile, covering both data structures and behaviors.
TypeScript has some unique features—union and intersection types—that let you mix and match types in creative ways.
// Go inference example
func main() {
age := 30 // inferred as int
var name = "Alice" // inferred as string
}
Takeaway: TypeScript’s union and intersection types give you flexibility that Go doesn’t have, making TypeScript feel a bit more adaptable in mixed-type scenarios.
Here's where Go and TypeScript really part ways.
Go makes you deal with errors head-on:
// TypeScript inference example const age = 30; // inferred as number const name = "Alice"; // inferred as string
TypeScript follows JavaScript's lead with exceptions:
// Go generics example
func Print[T any](value T) {
fmt.Println(value)
}
func main() {
Print(123)
Print("Hello")
}
Go's way might seem wordy, but it forces you to think about what could go wrong. TypeScript's approach looks cleaner but might let you overlook some error cases.
Javier Perez from Stackademic puts it well:
"Go's error-handling might seem verbose, but it's got hidden benefits."
Go and TypeScript each have their strengths when it comes to backend development speed and scalability. Let's break it down.
Go is often considered the speed demon of the two. It's a compiled language, which gives it a big advantage over TypeScript in how fast it runs.
In this benchmark by WWT you can see Go beating TypeScript (Node.js) hands down:
But hold up, there's more to the story these days. There are now many ways of speeding up TypeScript applications by using a different runtime or by enhancing the Node.js runtime.
For instance, in this benchmark we've shown that a TypeScript application using the Open Source Encore.ts framework can outperform a standard Node.js application (using Express.js) by 9x(!) measured in requests/second:
And as you can see, other frameworks like Elysia using the Bun runtime are also highly performant vs. standard Node.
So these days, it's fair to say for many web applications you will probably get sufficient performance from a TypeScript application.
Go's got a cool trick up its sleeve: goroutines. These are like lightweight threads that make it easy to build systems that can do many things at once.
Here's a quick example:
// Go example
func greet(name string) string {
return "Hello, " + name
}
func main() {
greet(123) // Boom! Compilation error: can't use an int as a string
}
TypeScript (on Node.js) does things differently. It's event-driven and non-blocking, which works well for many cases. But it can struggle with tasks that need a lot of processing power because it's normally single-threaded.
Here's how you might do something similar in TypeScript:
// TypeScript example
function greet(name: string): string {
return "Hello, " + name;
}
greet(123); // Nope! Error: number is not assignable to type string
TypeScript can be used to create multi-threaded applications, depending on the framework and runtime used.
For instance, when using Encore.ts you get multi-threading thanks to a Rust-based runtime that handles requests/validation/IO, integrated with Node.js using napi.
You can also replace Node.js with other runtimes to unlock multi-threading, for instance Deno and Bun[https://bun.sh/].
Go and TypeScript both pack a punch when it comes to backend development tools. Let's break down how they compare in terms of development environments and support.
Both languages have solid IDE support, but with a few key differences:

AI-enhanced Editors:
Go keeps it simple. Its standard library is big, so you often don't need many external packages. But finding the best packages can be tricky without organized repositories.
TypeScript taps into npm's huge ecosystem. This means lots of options, but you need to choose wisely as managing dependencies can quickly become as time-sink and security risk as your application grows.
Go and TypeScript take different approaches to package management:
Go uses a built-in module system:
TypeScript leans on npm (Node Package Manager):
Both languages come with solid testing options:

Your choice? It depends on your team's skills, project needs, and current tech stack.
Go or TypeScript for your backend? It's not a simple choice. Let's break it down.
Go is great when you need speed and simplicity:
TypeScript shines in these areas:
Your team's know-how matters:
If they know JavaScript, TypeScript is an easy step. Airbnb did this for their big codebase.
Got a mix of coders? Go's simple syntax could work well for everyone.
Learning curve? One way of looking at it is this: Go has 25 keywords, while TypeScript has over 60. However, TypeScript has a more mature ecosystem of libraries and frameworks, meaning there's likely less knowledge required to solve for common startup use cases.
Go or TypeScript for your backend? It's not a one-size-fits-all choice, it depends on your situation. For example:
Go is your go-to when speed and simplicity matter most. It's great for building systems that need to handle a lot and do it fast.
Here's why Go stands out:
TypeScript shines when you need strong typing in a JavaScript world or for big web apps. Its perks:
So, how do you choose?
Think about:
What does your project need? High performance? Go might be your answer. Web-focused? Maybe TypeScript.
What does your team know? JavaScript pros might prefer TypeScript.
Speed of development or speed of running? Go runs faster, but TypeScript might let you build quicker.
What tools and support can you tap into? TypeScript has the JavaScript world behind it. Go's community is growing fast.
How easy will it be to keep your code clean long-term?
Bottom line: Neither is "better" overall. They're good at different things. Pick based on what you need and what your team knows.
Both languages have their strong points. Think about what your project needs, what your team knows, and how easy it'll be to maintain in the long run when you're deciding.
That’s it! Hopefully you know what language to reach for in your next project.
