how to use the isthursday function from the date-fns library in typescript

To use the isThursday function from the date-fns library in TypeScript, you first need to install the date-fns package and its associated type definitions. You can do this using the following commands:

npm install date-fns
npm install -D @types/date-fns

Once you have installed the package and the type definitions, you can import the isThursday function and use it in your TypeScript code. Here's how to do it:

index.ts
import { isThursday } from 'date-fns';

if (isThursday(new Date())) {
  console.log('Today is Thursday!');
} else {
  console.log('Today is not Thursday.');
}

In the example above, we first import the isThursday function from the date-fns module. We then pass a new Date instance to the function, which returns true if the given date is a Thursday and false otherwise. Finally, we log a message to the console depending on the result of the function call.

Note that the isThursday function takes an optional second argument, which is an object containing options to customize its behavior. You can refer to the date-fns documentation for more information on how to use this function and its options.
