Typescript Duplicate Function Implementation


I'm assuming your code looks like this:

public emit<T1>(event: string, arg1: T1): void {}public emit<T1,T2>(event: string, arg1: T1, arg2: T2): void {}public emit(event: string, ...args: any[]): void {    // actual implementation here}

The problem is that you have {} after the first 2 lines. This actually defines an empty implementation of a function, i.e. something like:

function empty() {}

You only want to define a type for the function, not an implementation. So replace the empty blocks with just a semi-colon:

public emit<T1>(event: string, arg1: T1): void;public emit<T1,T2>(event: string, arg1: T1, arg2: T2): void;public emit(event: string, ...args: any[]): void {    // actual implementation here}
