For Loop as While Alternative

Snippet

For Loop as While Alternative

Go has only one loop keyword: `for`. There is no `while` keyword. The `for` loop without initialization and post statements acts as a while loop. This makes Go simpler while remaining powerful.

snippet.go
go
package main
 
import "fmt"
 
func main() {
    count := 0
    
    // Go has no while keyword, for is used instead
    for count < 5 {
        fmt.Println("Count:", count)
        count++
    }
    
    // Classic for loop
    for i := 0; i < 3; i++ {
        fmt.Println("i:", i)
    }
}

Breakdown

for count < 5 { }

For without init/post becomes a while-like loop, runs while condition is true

count++

Increment operator increases count by 1 each iteration

for i := 0; i < 3; i++

Classic three-part for loop with initializer, condition, and increment
