[Golang] Make Slice Empty
After a slices contains some items and we want to empty the slice, how to write the syntax?
Use int array as example, the syntax is:
myArray = []int{}
See the following full example on Go Playground.
package main
import (
"fmt"
)
func printNumbers(numbers []int) {
for _, number := range numbers {
fmt.Println(number)
}
}
func main() {
// initialize int slice
var numbers = []int{1, 2, 4, 5}
printNumbers(numbers)
// make slice empty
numbers = []int{}
printNumbers(numbers)
}
Tested on: Go Playground
