Understanding the code is critical for the project's success: you always need to know what it does precisely and estimate the time and memory it will use. Packages instead of classes, no type inheritance, etc., in Golang syntax helps to achieve great clarity of the code. Another factor - the independence of code segments is important for its overall maintainability and the possibility of modifications. As mentioned above, it is a procedural language, so there are strict programming rules and established ways to perform a task. Apparently, code complexity is often an obstacle to the smooth work of a big team.

Go is based on C syntax but taken to a new level for safer memory management and prevention of memory leakage. Stable and straightforward syntax, code readabilityĪs we already mentioned, simplicity was among the reasons to create Golang. All in all, Go is a powerful tool in terms of concurrency, while the concurrency execution code is simple and beautiful. Goroutines have several other merits compared to threads. Golang has an equivalent of threads - goroutines, which are lightweight, take only 2KB of memory - and millions can be spun simultaneously. Creating micro-threading apps might also be a solution, but with many programming languages, it is hard and not memory efficient. It's what makes it well-suited for big scalable applications. Thanks to many built-in features, Golang has concurrency, which means that the app will perform multiple tasks simultaneously on one CPU. To maintain database connections, message queues, and caches, they require numerous microservices. As applications grow, they need to process multiple sub-tasks. There is an upward tendency for a higher number of processor cores to enhance performance, for instance, in data centers. What Are the Main Advantages of Using Golang? Performance and scalability Let's have a closer look at Golang's advantages compared to other languages, the value it can create for a project, and the type of projects it is best suited for. In his presentation at the Gopherpalooza Conference 2019 (one of the 27 devoted to Go held that year), Robert Griesemer mentioned the main strengths of his child - simplicity, strong typing, concurrency, garbage collection, fast compilation times, and ease of use. Thus, the idea of a new language appeared. So, all the characteristics required by the Google team were not available with most programming languages. At that time, neither JavaScript nor Python had strong typing.

At Google, C++ and Java dominated server programming, and neither was easy to use. Naturally, there was also a pressing market need for a language that could support the development of more responsive and faster apps. Although it wasn't the first smartphone on the market, it caused a mobile app revolution - from just 500 apps available on App Store as it first launched in 2008, to more than 2 million now - only there. How did it all start? In 2007, the iPhone was introduced.

What is goland used for software#
The purpose of creating Golang was to eliminate the unnecessary complexity of the software development process and address scalability issues. Google has thousands of programmers who deal with large server software hosted on countless clusters. They brainstormed it in 2007 but published two years later after refinement. To solve this, can follow below.This procedural (systematic and well-structured) coding language was designed by Google's lead developers - Rob Pike, Ken Thompson, and Robert Griesemer. It has the same issue as the first one mentioned above. block main 1ms to wait goroutine finished Loop and get pointer of each elementĪssume there is a code snippet like below which is to get the pointer of each element in an array and create a new array with the corresponding pointer. In this post, some tricks and tips would be talked about regarding for range. Many people find that for range is very convenient when don't care about the index of the element. GoLang provides two major ways to loop through elements of array, slice and map.
