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

To use the isTuesday function from the date-fns library in TypeScript, you first need to install the package. You can do this using npm or yarn:

or

yarn add date-fns

2 lines

Once you have installed the package, you can import the isTuesday function from the date-fns library in your TypeScript code like this:

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

2 lines

You can then use the isTuesday function to check if a given date is a Tuesday. Here's an example:

index.ts
const someDate = new Date('2021-11-30');

if (isTuesday(someDate)) {
  console.log('Today is Tuesday!');
} else {
  console.log('Today is not Tuesday.');
}

In this example, we create a new Date object using the Date constructor, passing in the string '2021-11-30' as the argument. We then call the isTuesday function, passing in the someDate variable as the argument. The isTuesday function returns a boolean value that indicates whether the specified date is a Tuesday. We then use an if statement to check the value of the boolean, and log a message to the console depending on whether the date is a Tuesday or not.
