Mojo Takes a Big Leap Forward: Embracing Open Source!
Mojo Embraces Open Source: Building a Language Together Modular is excited to announce a major milestone for Mojo, their innovative programming language: the core modules from the Mojo standard library are now open-source! This decision underscores Modular’s belief that open-source collaboration is the key to unlocking Mojo’s full potential. Why Open Source? A Better Future…
Konika SitoulaInterface Pollution in Golang
Interfaces are one of the cornerstones of the Go language when designing and structuring our code. However, like many tools or concepts, abusing them is generally not a good idea. Interface pollution is about overwhelming our code with unnecessary abstractions, making it harder to understand. So, first we understand the concept of interface and then…
Bibek PokhrelNot being aware of the possible problem of type embedding
Concept of embedded field A struct field without a name is known as embedded field. For example :- In the Employee struct, the Address type is declared without an associated name; hence, it’s an embedded field. But this can sometimes lead to unexpected behaviors if we don’t understand all the implications of type embedding. Note…
Avinaya AcharyaBeing confused about when to use generics
Introduction The Go 1.18 release introduced a new feature called generic types (commonly known by the shorter term, generics). This allows writing code with types that can be specified later and instantiated when needed. However, it can be confusing about when to use generics and when not to. In this blog, I will try to describe the concept…
BABULAL TAMANGReturning Interfaces
While designing a function signature, we may have to return either an interface or a concrete implementation. Let’s understand why returning an interface is, in many cases, considered a bad practice in Go. We know that interfaces live, in general, on the consumer side. Let us consider, there is producer package, we define an producerstore…
Bibek PokhrelOptional Function Parameter Pattern
Go doesn’t support optional function parameters. However, the need for optional parameters will always exist. There are many ways to provide optional parameters to a function in Go, but the most graceful way is to use functional options. Do in this blog we will go through a concrete example and covers different ways to handle…
Avinaya AcharyaProject misorganization
Project organization is one of the most common mistake made by Go Developer. Go provides a lots of freedom for designing the packages and modules hence it is not easy task to organize the project. is The purpose of organizing the project are maintainability, readability, consistency and so on.
BABULAL TAMANGAny says nothing
The interface type that specifies zero methods is known as the empty interface: interface{} An empty interface may hold values of any type. (Every type implements at least zero methods.) Empty interfaces are used by code that handles values of unknown type. With Go 1.18 the predeclared type any became an alias for an empty…
Bishow ShresthaCreating utility packages
This blog is about how it is a bad practice to create shared packages such as utils, common and base. We will learn about the problems with such approach and how we can improve our code and project structure by avoiding such an approach. Let’s look at an example inspired by the official Go blog….
Bibek PokhrelCreating confusion with octal literals
Octal is a number system with base 8, it has 8 values (0, 1, 2, 3, 4, 5, 6, and, 7). In Go programming language, an octal literal can be written with the prefix 0 (Zero). The value which is prefixed with 0 is considered as an octal value and it can be used in the program statements like…
