Let's say I have a custom interface called MyInterface
Is there a built-in method in TypeScript that allows checking if an object adheres to the MyInterface ?
Something similar to using instanceof but for interfaces instead of classes.

From my understanding, there doesn't seem to be a direct way to achieve this using `instanceof` as I have personally attempted multiple times. However, it does work with classes.
Therefore, the alternative approach would be to inspect the properties of the object, for example:
if((object as SomeInterface).interfaceMethod)){
// This object implements SomeInterface
} else {
// This object does not implement SomeInterface
}
If you're looking for a way to perform runtime tests and validations in TypeScript, one option is to utilize the ts-interface-checker module.
This module requires a runtime description of the interface, which can be easily generated from TypeScript interfaces using the ts-interface-builder companion module.
