Why can’t Go language collect?

The reasons why go language cannot collect: 1. Using go language slices can achieve similar functions to collections and is more efficient than collections in other languages; 2. Go language gives up in order to maintain the simplicity and efficiency of the language. Collections are focused on simplicity and readability; 3. Go language provides a powerful standard library and third-party libraries, and various data structures and algorithms in the standard library can be used to implement collection operations; 4. Go language is flexible The interface and type system make it easy to define and use custom types, and create your own collection types by defining appropriate structures and methods.

Why can’t Go language be aggregated?

As the demand for software development continues to grow, there is one language that is becoming more and more popular. This language is the Go language, also known as Golang. The Go language was developed by Google to enhance the advantages of existing programming languages ​​and eliminate some of the disadvantages. However, despite the many powerful functions and features of the Go language, it does not have a built-in collection type. This raises the question: why can't Go collect?

First, let’s understand what a set is. In other programming languages, a set is a data structure that can store multiple elements. You can use collections to store and manipulate multiple pieces of data, such as integers, strings, or structures. Common collection types include arrays, lists, sets, and dictionaries. These collection types provide convenient methods to add, remove, and access elements in the collection.

However, Go language abandoned the traditional collection type. Instead, it provides a simple and efficient data structure called a slice. A slice is a dynamic array that can change size and provide access to the underlying array. Using slices can achieve similar functions to collections and is more efficient than collections in other languages.

Secondly, one of the reasons why the Go language does not provide other collection types is to keep the language simple and efficient. One of the design concepts of the Go language is "Simplicity is beautiful", which focuses on simplicity and readability. In the design of the language, the Go language avoids too many complex functions and instead provides some basic data structures and operations. The benefit of this is that it reduces learning costs and code complexity, making it easier to write and maintain code.

In addition, the Go language also provides powerful standard libraries and third-party libraries that can be used to solve various problems, including set operations. Although the Go language does not have a built-in collection type, collection operations can be implemented using various data structures and algorithms in the standard library. For example, you can use map to implement dictionaries, you can use slicing and indexing to implement lists, you can use structures and methods to implement sets, etc. These libraries provide functionality similar to collections in other languages ​​and provide efficient implementations.

Finally, although the Go language does not have a built-in collection type, you can implement a custom collection type as needed. The Go language has a flexible interface and type system that makes it easy to define and use custom types. By defining the appropriate structures and methods, you can create your own collection types and integrate them seamlessly with other libraries and code. This flexibility makes implementing collections in Go easy and highly customizable.

In summary, although the Go language does not have a built-in collection type, collection operations can still be implemented by using slices, standard libraries, and custom types. The Go language chose to abandon traditional collection types in order to maintain simplicity and efficiency, and to provide simpler and more readable code. Therefore, although collection types cannot be used directly, collection functionality can be implemented in the Go language using other methods.
