Go Code Review Comments

 

Code review comments in Go programming (or any language) are critical feedback provided to developers during the code review process to ensure code quality, maintainability, and adherence to best practices. The goal of code reviews is to identify potential issues, improve code readability, and promote consistency across the codebase.

Common code in Go focus on several key aspects:

  1. Readability and Maintainability: Comments may address variable naming, function clarity, and the use of clear and idiomatic Go syntax to enhance code readability and maintainability.
  2. Error Handling: Go emphasizes explicit error handling. Review comments may suggest proper error checking and handling strategies to ensure robustness and reliability of the code.
  3. Performance and Efficiency: Comments may highlight potential performance bottlenecks or inefficient code patterns, suggesting optimizations or alternatives.
  4. Concurrency and Goroutines: Go’s concurrency model using goroutines and channels requires careful handling. Review comments may address proper synchronization and concurrency patterns.
  5. Testing: Encouraging comprehensive testing coverage and proper use of Go’s testing framework to ensure code correctness,

Single-line comments is start with two forward slashes ( //  ).

Ex:       // this is a single-line comment.

         // fmt.Println("This line does not execute")

  • Multi-line comments

Multi-line comments start with /* and ends with */  .

package main
import ("fmt")

func main() {

  /* The code below will print Hello Prwatech
  to the screen, and it is amazing */

  fmt.Println("Hello Prwatech!")
}

Output:

PS C:\GO_Language\datatype> go run float1.go
  
Type: float32, value: 23.78
Type: float32, value: 3.4e+38

 

  1. Program to demonstrate the Example of print() function 
    package main

// Main Function
func main() {
    Name := "Sandeep"
    Age := 23
  /* The code below will print Name and Age
 in a sentence  to the screen, and it is amazing */

    print(Name, " Age is ", Age, "Year")
}

    Output :

    PS C:\GO_Language\datatype> go run float1.go
  
Type: float32, value: 23.78
Type: float32, value: 3.4e+38
  2. Program to illustrate print function and multi-line comment. 
    package main
import “fmt”
func main() {
    book := "AI-ML Machine Learning "
    price := 21
  /* The code below will print book and price
 in a sentence to the screen, and it is amazing */

    print(book, " price is ", price)
}

    Output :

    PS C:\GO_Language\datatype> go run float1.go
  
Type: float32, value: 23.78
Type: float32, value: 3.4e+38
  3. Program to illustrate Scan() & print(). 
    package main

import "fmt"

func main() {

    var name string
    var age int
    print("Enter Name :")
    fmt.Scan(&name)   //scan the input value 
    print("Enter Age :")
    fmt.Scan(&age)
  /* The code below will print Name and age
 in a sentence to the screen, and it is amazing */

    fmt.Printf("My name is  %s I am  %d years old.", name, age)
}

    Output:

    PS C:\GO_Language\datatype> go run float1.go
  
Type: float32, value: 23.78
Type: float32, value: 3.4e+38
