TypeScript: solution with Overloaded Function Signatures and This Context in Class Methods
I'm stuck on something that should probably be simple. I'm working with an scenario with overloaded function signatures in TypeScript when trying to use them in class methods. I have a class that is supposed to handle different types of data processing based on the input type. Here’s a simplified version of my code: ```typescript class DataProcessor { process(data: string): string; process(data: number): number; process(data: boolean): boolean; process(data: any): any { // Method logic here return data; } } const processor = new DataProcessor(); const result1 = processor.process("Hello"); // Should return a string const result2 = processor.process(10); // Should return a number const result3 = processor.process(true); // Should return a boolean ``` When I run this code, I expect the method to return the same type as the input. However, I am getting the following behavior when trying to call `processor.process(10)`: ``` Argument of type 'number' is not assignable to parameter of type 'any'. ``` I've tried ensuring that the method signatures correctly reflect the intended overloads, and I even added the `any` type to see if it would help, but the behavior continues. I’m also using TypeScript version 4.8.4. Is there something I’m missing regarding the `this` context or how TypeScript handles overloads in class methods? Any insights would be greatly appreciated! This is part of a larger application I'm building. Has anyone else encountered this?
