TypeScript class not properly enforcing method parameter types when used as callbacks
I'm deploying to production and I've been researching this but I'm getting frustrated with I'm working on a personal project and I'm relatively new to this, so bear with me. I'm working with an scenario with method parameter types not being enforced correctly when my TypeScript class methods are passed as callbacks. I'm using TypeScript 4.5 and have a class that resembles the following structure: ```typescript class User { constructor(public name: string, public age: number) {} public displayInfo(greeting: string): string { return `${greeting}, my name is ${this.name} and I am ${this.age} years old.`; } } const user = new User('Alice', 30); const greetFunction = user.displayInfo; ``` The question arises when I try to use `greetFunction` as a callback: ```typescript function executeGreeting(callback: (greeting: string) => string) { console.log(callback('Hello')); // behavior occurs here } executeGreeting(greetFunction); ``` When I run this code, I get a TypeScript behavior: `Argument of type '(greeting: string) => string' is not assignable to parameter of type '(greeting: string) => string'.` It seems that TypeScript is unable to infer the correct `this` context when `greetFunction` is passed as a callback. I've tried binding the method explicitly using `bind`: ```typescript executeGreeting(greetFunction.bind(user)); ``` This does work, but it feels cumbersome, and I was expecting that TypeScript would automatically handle the `this` context on its own when calling the method in this way. Is there a better approach to ensure that my class methods maintain their context when passed as callbacks without having to bind them every time? My development environment is Ubuntu. Is there a better approach? This is happening in both development and production on Linux. Hoping someone can shed some light on this. I'm working with Typescript in a Docker container on Windows 11. What are your experiences with this?
