Discuss some problems and shortcomings of Golang language

Golang language has been highly sought after by developers since its inception. Its efficient concurrency processing, concise syntax, excellent compilation speed and other features have been widely praised. However, at the same time, in some application scenarios, the Golang language also exposes some shortcomings. This article will explore some of the problems and shortcomings of the Golang language.

1. Focusing too much on the bottom layer
The bottom layer of the Golang language and concurrency are also its advantages, but it also focuses on showing the underlying details to software developers. This not only hinders the rapid popularity of the Golang language, but also causes some problems in the program. In other words, you can know these low-level details during the development process and make adjustments accordingly. However, too many such details will affect the developer's efficiency too harshly, making developers pay more attention to the low-level rather than developing high-level abstractions. ization program.

2. Limitations on error handling
The Golang language provides a simple error handling mechanism as part of the language to handle exceptions. While this error handling mechanism is easy to understand and use, it has limitations in understanding complex error codes and presenting data. Additionally, it only provides one error type, which means more work for developers to implement different kinds of error handling.

3. Package Management
Although Golang has received a lot of attention, its package management function has always been unreliable. Due to the underlying development architecture, it is difficult for Golang developers to easily use external libraries to enhance their applications. This increases the complexity of reusing existing code since all dependencies need to be declared again from one project to another.

4. Lack of Generics
The Golang language lacks generics, which is a shortcoming known to many developers. Reuse is difficult to achieve without generics because the same code needs to be recreated in all scenarios. This becomes especially evident in creating and managing collections and data structures. This means that a lot of code must be written repeatedly during the program writing process, which consumes time and energy and is prone to errors.

5. Problems with Reflection
The reflection mechanism of Golang language is limited because it cannot fully cover all types and objects in the program. Therefore, when the program needs to refer to some weaned objects, the developer needs to define a structure to handle these specific objects. In some cases, this is often time-consuming and cumbersome.

To sum up, Golang language is an excellent language, but it also has shortcomings. Problems such as too much attention to low-level details, limitations in error handling, unreliable package management, lack of generics, and problems with reflection need to be paid attention to and overcome. In actual development, developers need to balance the need to write efficient and scalable programs with the requirement of the Golang language to expose details.
