## prevent last false

function body should not end up with a ternary statement

### wrong last

Compound of 2 'false' statement returns false.

```bash
[[ : ]] && [[ : ]]
```

### right last

```bash
[[ : ]] && [[ : ]] || true
```

## arithmetic issue

last (++) statement does not complete successfully!

### wrong ++

```bash
count=0
(( ++count )) # ok 
(( ++count )) # last statement in function returns false
```

### right ++

```bash
count=0
count=$((count+1))
```
