Rule Details

This rule aims to keep the source code as maintainable as possible by reducing the amount of overloads.

Examples of incorrect code for this rule:

function f(x: number): void;
function f(x: string): void;

f(): void;
f(...x: number[]): void;

Examples of correct code for this rule:

function f(x: number | string): void;

function f(x?: ...number[]): void;
