# wastedassign
`wastedassign` finds wasted assignment statements
found the value ...
- reassigned, but never used afterward
- reassigned, but reassigned without using the value
## Example
```go
package main
import "fmt"
func f() int {
a := 0
b := 0
fmt.Print(a)
fmt.Print(b)
a = 1 // This reassignment is wasted, because never used afterwards. Wastedassign find this
b = 1 // This reassignment is wasted, because reassigned without use this value. Wastedassign find this
b = 2
fmt.Print(b)
return 1 + 2
}
```
```bash
$ go vet -vettool=`which wastedassign` sample.go
# command-line-arguments
./sample.go:10:2: assigned to a, but never used afterwards
./sample.go:12:2: assigned to b, but reassigned without using the value
