What is the conflict between the design philosophy of Go language and set operations?

As a modern programming language, Go language has the characteristics of simplicity, efficiency, and good concurrency, and is deeply loved by programmers. However, when performing collection operations, it is sometimes found that there are some conflicts between the design philosophy of the Go language and some traditional collection operation methods. This article will elaborate on the design concept and code examples to explore the conflicts that may occur when performing set operations in Go language.

First of all, let’s talk about the design concept of Go language. One of the design goals of the Go language is simplicity and efficiency. It advocates using less code to achieve more functions to improve program readability and maintainability. The designers of the Go language believe that concise code is easier to understand and debug, and is more conducive to team collaboration. Therefore, the Go language strives to be simple and intuitive in the design of its syntax and standard library.

However, it is this simple and efficient design concept that may cause some conflicts when performing collection operations. Traditional collection operation methods usually encapsulate the underlying data structure and provide rich functions and operation methods, but this may also lead to lengthy and complex code. In Go language, the collection operation method is relatively simple, and the elements and logic of the operation need to be handled by the programmer himself. This requires programmers to pay more attention when writing code to avoid lengthy and repetitive code.

Next, we will use specific code examples to illustrate the conflict between the design philosophy of the Go language and collection operations. Let's take a simple array deduplication operation as an example to compare the traditional collection operation method with the Go language implementation.

The first is the implementation of the traditional set operation method:

def remove_duplicates(arr):
    result = []
    for ele in arr:
        if ele not in result:
            result.append(ele)
    return result

The above code uses the Python language to implement the deduplication operation on the array, by traversing the array and determining whether the element is already in the result set To achieve deduplication.

The following is the code that uses the Go language to achieve the same function:

func removeDuplicates(arr []int) []int {
    seen := make(map[int]bool)
    result := []int{}
    for _, ele := range arr {
        if _, ok := seen[ele]; !ok {
            seen[ele] = true
            result = append(result, ele)
        }
    }
    return result
}

In the Go language, we need to maintain a map ourselves to record whether the element has appeared before, in order to achieve the purpose of deduplication. . Compared with the traditional method, you need to write more code to manage the map to achieve the same function.

Through the above two code examples, it can be seen that when performing collection operations, traditional collection operation methods usually provide more encapsulation and functions, making the operation more convenient. In the Go language, due to the simplicity and efficiency of the design concept, programmers need to manage some details themselves, which may increase the amount of code and complexity.

To sum up, the conflict between the design concept of Go language and set operations is mainly reflected in the balance between simplicity and functionality of operations. In daily programming, programmers can choose appropriate collection operation methods according to specific needs and scenarios to achieve concise and efficient code.
