how to use the isprototypeof function from the lodash library in typescript

To use the isPrototypeof function from the Lodash library in TypeScript, you can install the @types/lodash package using npm. This package contains the type definitions for Lodash, allowing TypeScript to understand the function signatures and types.

npm install --save-dev @types/lodash

Then, you can simply import the isPrototypeof function and use it in your code.

index.ts
import * as _ from 'lodash';

class MyClass {
  // ...
}

const myInstance = new MyClass();

if (_.isPrototypeof(myInstance, MyClass)) {
  console.log('myInstance is an instance of MyClass');
} else {
  console.log('myInstance is not an instance of MyClass');
}

The first argument of the isPrototypeof function is the object to check, and the second argument is the constructor function that the object should be an instance of. The function returns true if the object is an instance of the constructor function's prototype, and false otherwise.

Note that you need to import the lodash library using the * as _ syntax in order to use the isPrototypeof function. This is because Lodash uses a default export, which isn't compatible with the ES6 module syntax that TypeScript uses by default.
