|
|
|
|
Members of TypeScript enums and namespaces are generally retrieved as qualified property lookups: e.g. `Enum.member`.
|
|
However, when accessed within their parent enum or namespace, the qualifier is unnecessary: e.g. just `member` instead of `Enum.member`.
|
|
This rule reports when an enum or namespace qualifier is unnecessary.
|
|
|
|
## Examples
|
|
|
|
<Tabs>
|
|
<TabItem value="❌ Incorrect">
|
|
|
|
```ts
|
|
enum A {
|
|
B,
|
|
C = A.B,
|
|
}
|
|
```
|
|
|
|
```ts
|
|
namespace A {
|
|
export type B = number;
|
|
const x: A.B = 3;
|
|
}
|
|
```
|
|
|
|
</TabItem>
|
|
<TabItem value="✅ Correct">
|
|
|
|
```ts
|
|
enum A {
|
|
B,
|
|
C = B,
|
|
}
|
|
```
|
|
|
|
```ts
|
|
namespace A {
|
|
export type B = number;
|
|
const x: B = 3;
|
|
}
|
|
```
|
|
|
|
</TabItem>
|
|
</Tabs>
|
|
|
|
## When Not To Use It
|
|
|
|
If you explicitly prefer to use fully qualified names, such as for explicitness, then you don't need to use this rule.
