The way Rust handles memory management means that it doesn’t need a garbage collector, unlike Go, and the use of references let objects easily get passed around without requiring copies to be made. Right off the bat, there are clear differences between Go and Rust. Go has a stronger focus on building web APIs and small services that can scale endlessly, especially with the https://cryptonews.wiki/ power of Goroutines. The latter is also possible with Rust, but things are much harder from a developer experience point of view. The same concurrency and networking features align with its high portability across various platforms make Go an exceptional language for cloud computing. As a matter of fact, many stand-out cloud platforms like Kubernetes were built with Go.
To paraphrase the indie band Cracker, what the world needs now is another programming language like I need a hole in the head. That said, Go has slowly but surely inundated the development world like a creeping vine, covering everything that came before it in a lush—and in many ways superior—cover of programming power. With its growing popularity, there are a number of reasons you should take a closer look at it. As you might guess, we power the Bitly ecosystem with a collection of web apps, APIs, microservices and datastores.
- Meanwhile, with Java, you can use the same jar anywhere you have the JVM.
- You can pass them to other functions to use, but if you want to use them in your own code, all you’d have so far is an empty context.
- Additionally, the standard library includes things like TLS and SQL support, so you can be very productive in Go very quickly.
For example, a website may provide you with local weather reports or traffic news by storing data about your current location. Above all, however, Go enabled Twitch to improve 20 times the GC factor responsible for automatically managing dynamically allocated memory. It is used there for the geofence service, Embedded system Wikipedia which serves the user’s location and product availability. Geofence makes it possible to precisely define the area with special requirements (e.g. taking into account places such as airports) and to implement dynamic prices. In addition, external libraries may be of low quality and may not be secure enough.
It’s A Young Language
In a regex test—regex-redux —Go ran in 3.55 seconds while Java ran in 5.58. The Go program weighed in at 102 lines of code, while the Java program weighed in at 70. True, Go was a little heftier than Java, but given the speed at which Go bested the next most popular system language, it’s clear you’re not sacrificing speed. For web apps, goroutines let you run concurrent jobs while avoiding roadblocks.
One benefit of using context.Context in a program is the ability to access data stored inside a context. By adding data to a context and passing the context from function to function, each layer of a program can add additional information about what’s happening. For example, the first function may add a username to the context.

Google Cloud also uses Go to enhance scalability and performance. In contrast to interpreted languages, compiled languages are directly translated to machine code before execution. With enhanced memory performance and support for several IDEs, Go powers fast and scalable web applications. Both Go and Python are easy to get started with for beginners and are relatively easy to learn. Go is a simpler language and may be mastered more quickly, but some find getting started more difficult than Python, which takes longer to master as there’s more to learn.
- Do you think creators of systems programming languages like C/C++, Rust etc. were stupid since they don’t do the same?
- Golang is advanced and reliable, offering great built-in ways to handle errors.
- Right now, in Go’s development, Go is mostly used for server-side applications.
- Syntactically similar to C, you can also find memory safety, garbage collection, structural typing, and concurrency in Go.
Other times, you don’t care about the specific time a context ends and you just know you want it to end one minute after it’s started. It’s possible to do this using context.WithDeadline and other time package functions and methods, but Go also provides the context.WithTimeout function to make that work easier. When the ctx.Done branch is called, the code uses the Err function provided by context.Context to determine how the context ended. Since your program is using the cancelCtx function to cancel the context, the error you see in the output is context canceled.
We leverage them pretty heavily to test our code and as a tool to create modular code. For example, we set out early on that we would have a common datastore interface in all our services. This is an interface that every one of our services 14 Great Apps to Listen to Music Without Wifi iOS and Android use in order to interact with a data source. The real win with the channel-based design came when migrating from one observability backend to another. Riot recently moved all metrics and logs from a hand-rolled pipeline to New Relic.
When it comes to hiring developers, there is always more brunt work than expected. But this is relatively new compared to the most traditional languages like Java and Python, which were released in the 1990s. Many old infrastructures were rewritten using Go in an attempt to modernize what’s become obsolete over time. A new version of the Network Time Protocol – an internet protocol for clock synchronization among networks – relies on Go. Structural typing extends more flexibility towards Go users by determining class via structure rather than declarations.

A popular saying about Go is that you can read and digest the entire Go spec in an afternoon. Many developers who have dived into Go agree it’s easy to pick up compared to other languages. Go is an open-sourced programming language that was first published in 2009 and developed by Google’s Rob Pike, Robert Griesemer, and Ken Thompson.
Everything should be really obvious for an external code reviewer and a programmer should understand all the mechanisms for how the Go code uses the memory, file system, and other resources. If my experience with programming has taught me anything, it’s that there is no silver bullet when it comes to software development. I’ll detail below how one traditional language and one new kid on the block worked in my experience. For instance, SoundCloud – an online audio distribution platform, is one of the early adopters of Golang. Enterprises and businesses worldwide are turning towards the adoption of Golang for their web apps or cloud-based projects requiring higher speed, scalability and security. Compared with the code of other languages, python code is easy to write and debug.
Go supports concurrency, on the other hand Python, doesn’t have any in-built concurrency mechanism. If you’re just starting out with Rust, it might be a good idea to brush up on this beginner’s guide before you read any further. The busy bustle of everyday life requires technology that can accommodate the everyday person who needs fast and reliable service. The best example of a service like this is Uber which uses Go to get to users in the nick of time for just about every request. Gotests provides an easy way of generating table-driven tests via core logic. Revive extends a framework for the development of custom rules in Go.
Go contains a simple API allowing developers the environment for easy testing, profiling, and much more. This also allows for older devices to enjoy Go-based apps due to the simple fact that they have less demanding system requirements. Go has the same performance as C, but it is much easier to maintain than Java. Without the need for a virtual machine, Go boasts easier maintenance and no warming up period. These and many other characteristics are what make Golang stand out from its competitors. So, let’s have a look at some of the other advantages when using Golang.
Build a web application with Hono
According to Hired, Go is the #1 most in-demand programming language across the planet. Companies are gaining more awareness of how beneficial using Golang can be for their businesses, and programmers are brushing their skills of the language in droves. As an open-source initiative, you’ll have no issues in getting the development tools for your team. There are various editors, IDEs, and plugins that you can download from the GitHub repository for Go.A handful of cloud-based IDEs that support Go are also available.
Go is a modern programming language originally developed by Google that uses high-level syntax similar to scripting languages. It is popular for its minimal syntax and innovative handling of concurrency, as well as for the tools it provides for building native binaries on foreign platforms. The context deadline exceeded error may also be familiar to you if you’ve used Go applications or looked at their logs in the past. This error is common to see in web servers that take some time to complete sending responses to the client. If a database query or some processing takes a long time, it could cause the web request to take longer than is allowed by the server. Once the request surpasses the limit, the request’s context would be canceled and you’d see the context deadline exceeded error message.
After spending years sticking to conventional programming languages, why should tech business founders use Golang? That’s one of the buzzing questions that founders will be asking, as Go language is getting more prominence. By the way, the blog post does not mention the low memory footprint and fast startup time of Go applications inside containers. The only way to compare performance with java is to run it several times in a single startup. Furthermore the JIT optimizes the code on the fly through each run until it gets marked as no longer optimizable.

This plays into the prevention of runtime errors, improving runtime efficiency. Go also has a vibrant and active open-source community that develops modules and libraries, helps newcomers, and contributes to the Go project itself. Go is a language that can do a lot, from infrastructure to the web to data processing.
