@ -4,6 +4,34 @@ Simplified result/error handling for JavaScript.
|
|||
Grip always returns a consistent call result ready to be handled.
|
||||
It makes the control flow similar to that of Golang, but doesn't force you to make additional null checks or create transitional variables to hold error results.
|
||||
|
||||
Instead of returning an nullish Error, Grip always returns a Status object:
|
||||
|
||||
```javascript
|
||||
const [value, status] = grip(callable)
|
||||
if (status.Fail()) {
|
||||
// handle any error
|
||||
}
|
||||
if (status.Of(MySpecificError)) {
|
||||
// handle specific error
|
||||
}
|
||||
```
|
||||
|
||||
The call result is better than tuple:
|
||||
|
||||
```javascript
|
||||
const result = grip(callable)
|
||||
if (result.Fail()) {
|
||||
// handle any error
|
||||
}
|
||||
if (result.Of(MySpecificError)) {
|
||||
// handle specific error
|
||||
}
|
||||
|
||||
console.log(result.value) // result[0]
|
||||
```
|
||||
|
||||
Grip also works with Promises, functions that return promises, generators and async generators.
