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

To use the propertyIsEnumerable function from the Underscore library in TypeScript, you need to first import the library and the type definitions. You can do this by running the following command in your terminal:

npm install underscore @types/underscore --save

Once you have installed both the library and the type definitions, you can import the function and use it in your TypeScript code as shown below:

index.ts
import * as _ from "underscore";

const obj = { name: "John", age: 30 };

console.log(_.propertyIsEnumerable(obj, "name")); // Output: true
console.log(_.propertyIsEnumerable(obj, "toString")); // Output: false

7 lines

In the above code, we import the entire Underscore library as _, and then use the propertyIsEnumerable function to check if the name property is enumerable on the obj object. We then check the toString property to confirm that it is not enumerable. The output of the above code will be true and false, respectively.
