|
This rule extends the base [`eslint/comma-dangle`](https://eslint.org/docs/rules/comma-dangle) rule.
|
|
It adds support for TypeScript syntax.
|
|
|
|
See the [ESLint documentation](https://eslint.org/docs/rules/comma-dangle) for more details on the `comma-dangle` rule.
|
|
|
|
## Options
|
|
|
|
In addition to the options supported by the `comma-dangle` rule in ESLint core, the rule adds the following options:
|
|
|
|
- `"enums"` is for trailing comma in enum. (e.g. `enum Foo = {Bar,}`)
|
|
- `"generics"` is for trailing comma in generic. (e.g. `function foo<T,>() {}`)
|
|
- `"tuples"` is for trailing comma in tuple. (e.g. `type Foo = [string,]`)
