Imagine having a scenario with the following class:
class Example {
method1 = this.generateDynamicFunction((param: string) => {
return "string" + param;
});
method2 = this.generateDynamicFunction((param: number) => {
return 1 + param;
});
generateDynamicFunction(fn: (param: any) => any) {
return (param) => fn(param);
}
}
const instance = new Example()
instance.method1('text') // => stringtext
instance.method2(5) // => 6
How can I define the types for the functions Example.prototype.method1 and Example.prototype.method2? I aim to explicitly specify that method1 accepts and returns a string, while method2 accepts and returns a number.
Admittedly, this example is somewhat contrived. In my current project, I am in the final stages of revamping one of my message queue client libraries where many class functions are created dynamically. These functions share common functionalities but have varying input and output types.
