Go Language Keyword Guide

The Go language is A concise, efficient programming language whose keywords are used to control program flow, data types, and other language features. Mastering these keywords is crucial to understanding and writing Go code.

Basic keywords

  • #const: define a constant
  • func: define A function
  • type: defines a type
  • var: defines a variable
  • if: Conditional execution
  • else: Optional conditional branch
  • for: Loop execution
  • return : Return from the function

Data type related keywords

  • bool: Boolean value
  • string:String
  • int:Integer
  • float64:Floating point number
  • interface{}: Any type
  • map: Key-value pair collection
  • slice: Dynamic size array

Other keywords

  • break: Exit the loop
  • continue: Jump to the next part of the loop An iteration
  • defer: Defer function call execution until function exit
  • go: Execute function concurrently
  • select: Wait for events in multiple channels
  • range: Traverse elements in the sequence

Practical case

The following is a simple Go code example showing several keywords:

func main() {
    const name string = "John Doe"
    var age int = 30

    if age > 21 {
        fmt.Println(name + " is an adult.")
    } else {
        fmt.Println(name + " is a minor.")
    }

    for i := 0; i < 5; i++ {
        fmt.Println(i)
    }
}
Copy after login

In this example, we use const to define a constant string name, var to define an integer variable age, if and else to execute conditional branches, for to execute the loop.
