Complete list of go language keywords

The keywords of Go language are: basic keywords: const, func, type, var, if, else, for, return Data type related keywords: bool, string, int, float64, interface{}, map, slice Other keywords: break, continue, defer, go, select, range

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)
    }
}

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.
