In Golang there is no by default support of getters and setters, so it is optional. There are few advantage of using getters and setters event in golang and they are mentaion below :-…
Not 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…

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…
Creating confusion with octal literals

Ignoring the fact that elements are copied in range loops
Range is the form of for loop that iterates over a slice or map. We may forget or be unaware of how a range loop assigns values, leading to common mistakes. First, let’s remind ourselves how to use a range loop; then we’ll look at how values are assigned. Concepts A range loop allows iterating…
Using defer inside a loop
The defer keyword allows a function call to be postponed until the surrounding function has completed execution. This can be useful for reducing redundancy in code, such as when a resource needs to be closed after use. However, it’s important to be mindful of using defer within a loop, as it can have unintended consequences…
