I have a preference for using this form:
const myFunc = (): void => {}
over this one:
function myFunc(): void {}
However, TSLint insists on seeing:
interface MyFunc { (): void }
const myFunc: MyFunc = (): void => {}
I find the extra interface for the arrow function to be quite repetitive. Is there a way to maintain all type definition requirements for linting, but exempt arrow functions from this specific requirement without affecting other variables?
If you want to override the TSLint rule for variable-declaration within the typedef rule, you can do so by visiting
Alternatively, create your own generic function definition and utilize it as needed. Here's an example:
type CustomFunc<X, Y> = (x: X) => Y;
let customFunction: CustomFunc<void, void> = (): void => {};
let customFunction1: CustomFunc<number, string> = (num: number) => { return "example"; };
