how to use the isobject function from the underscore library in typescript

To use the isobject function from the Underscore library in TypeScript, you need to first install the library via npm:

npm install underscore

Then, you can import the isobject function from the library in your TypeScript file and use it with appropriate type annotations:

index.ts
import { isObject } from 'underscore';

const exampleObject: Record<string, unknown> = { foo: 'bar' };

if (isObject(exampleObject)) {
  console.log('exampleObject is an object');
} else {
  console.log('exampleObject is not an object');
}

In the above example, the exampleObject variable is annotated to be of type Record<string, unknown>, which indicates that it is an object with string keys and unknown values. The isObject function is then used to determine whether the exampleObject is in fact an object or not.

Note that type annotations are optional but recommended for TypeScript to be able to perform compile-time checks and catch any potential errors early.
