go run app.go always run in the background -

go1.8

how come following rund in background? have named file server.go , doing "go run server.go"

package main  import (     "fmt"     "net/http" )  func handler(w http.responsewriter, r *http.request) {     fmt.fprintf(w, "hi there x, love %s!", r.url.path[1:]) }  func main() {     http.handlefunc("/", handler)     http.listenandserve(":8080", nil) } 

vs code launch.json

{     "version": "0.2.0",     "configurations": [         {             "name": "launch",             "type": "go",             "request": "launch",             "mode": "debug",             "remotepath": "",             "port": 2345,             "host": "127.0.0.1",             "program": "${workspaceroot}",             "env": {},             "args": [],             "showlog": true         }     ] }
