The init() function in Go language is a special function that is automatically called when the program is executed to perform some initialization operations. In this article, we will deeply understand the execution sequence of the init() method in the Go language and demonstrate its role through specific code examples.
In the Go language, the init() function can appear in any package and can be defined multiple times. When the program starts, the init() function will be executed in the following order:
Below we use a specific code example to illustrate the execution sequence of the init() function:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 |

In the above code, when we execute the main program, the following sequence will be followed Execute the init() function:
Through this simple example, we can clearly see the execution order of the init() function and the dependencies between packages. In actual development, we can use the init() function to perform some necessary initialization operations to ensure the correct operation of the program.
In short, a deep understanding of the init() function of Go language is crucial to mastering the initialization mechanism of Go language. I hope this article can help readers better understand the execution sequence and role of the init() function.
