When working with multiple overloading functions in this code:
export function rect(a: Point, b: Point): Rect;
export function rect(a: Point, b: number|Point, c?: number): Rect;
export function rect(a: number|Point, b: number|Point, c?: number, d?: number ) {return new Rect(a,b,c,d);}
rect( 1,1,1, 1) // ts: "Expected 2-3 arguments, but got 4.ts(2554)"
A Typescript error occurs with the 4th argument. The cause of this issue is not obvious at first glance. However, when another overload with an additional argument is added:
export function rect(a: Point, b: Point): Rect;
export function rect(a: Point, b: number|Point, c?: number): Rect;
export function rect(a: number|Point, b: number|Point, c?: number, d?: number ): Rect ;
export function rect(a: number|Point, b: number|Point, c?: number, d?: number, e?: number ): Rect {return new Rect(a,b,c,d);}
rect( 1,1,1, 1)
The Typescript error disappears when making the function more flexible to handle additional arguments. This results in a smooth execution without errors even when passing a fifth argument to the 'rect' function.
This troubleshooting approach highlights the importance of having comprehensive overloads for better error handling and smoother code execution.
