golangHow to break FOR loop

package main
import "fmt"

func main() {
  nums := [5]int{1,2,3,4,5}
  for i, item := range nums {
    fmt.Printf("nums[%d] = %d \n", i, item)
    if ( i >= 1 ) {
      break
    }
  }
}ctrl + cgithub

`package main` default package declaration	`import "fmt"` loads `fmt` package to operate on strings (and print them)
`nums` array with 5 numbers we plan to iterate over	`i, item := range nums` iterate over `nums` while saving index to `i` and value to `item` on each iteration
`if ( i >= 1 ) {` sample condition to break loop on	`break` breaks current loop

Usage example

package main
import "fmt"

func main() {
  nums := [5]int{1,2,3,4,5}
  for i, item := range nums {
    fmt.Printf("nums[%d] = %d \n", i, item)
    if ( i >= 1 ) {
      break
    }
  }
}

output

nums[0] = 1 
nums[1] = 2
