Golang provides a built-in package called "encoding/json" that makes it easy to work with JSON.To encode a Go data structure into JSON, you need to annotate its fields with struct tags. These struct tags specify how the fields should be encoded in JSON. The most commonly used struct tags are "json" and "omitempty".

8 min readIn Golang, error handling is done using the built-in error type. When a function can encounter an error, it is generally recommended to return both the result and an error value. This allows the calling function to check if an error occurred and handle it appropriately.To handle errors effectively in Golang, you typically follow these steps:Functions should return both the desired result and an error - By convention, the last return value of a function should be of type error.

8 min readIn Go, a struct is a user-defined composite data type that allows you to group together related fields of different data types. It is similar to a class in object-oriented programming languages.To create a struct in Go, you use the type keyword followed by the name of the struct and define its fields within curly braces. Each field has a name and a type.

7 min readWorking with pointers in Go allows you to efficiently manage data and memory by providing direct memory addresses. Pointers in Go are represented using an asterisk (*) followed by the type of the pointer. Here's a brief explanation of how to work with pointers in Golang:Declaring a pointer: To declare a pointer, you can use the asterisk (*) symbol followed by the type of the variable it will be pointing to. For example, var ptr *int declares a pointer to an integer.
