To use the propertyIsEnumerable function from the date-fns library in TypeScript, you can follow the steps below:

    index.ts
    import { propertyIsEnumerable } from 'date-fns';
    
    49 chars
    2 lines
  3. Now, you can use the propertyIsEnumerable function in your TypeScript code as shown below:

    index.ts
    const date = new Date(2021, 9, 25);
    const isEnumerable = propertyIsEnumerable(date, 'getFullYear');
    console.log(isEnumerable); // Output: false
    
    144 chars
    4 lines

    In this code, we first create a Date object and then use the propertyIsEnumerable function to check if the getFullYear property of the Date object is enumerable or not. The function returns false because the getFullYear property of a Date object is not enumerable.

That's it! You have now successfully used the propertyIsEnumerable function from the date-fns library in your TypeScript code.
