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

To use the getdate function from the date-fns library in TypeScript, you first need to install the library and its types definitions using npm:

index.ts
npm install date-fns @types/date-fns
37 chars
2 lines

Then, you can import the getdate function and use it in your TypeScript code like this:

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

const date = new Date();
const year = getdate(date, 'yyyy'); // returns the current year as a string

console.log(`The year is: ${year}`); // outputs "The year is: 2022"
207 chars
7 lines

Note that getdate takes two arguments: a Date instance and a format string. The format string tells getdate how to format the date and what parts of it to return. In the example above, we're passing 'yyyy' as the format string, which tells getdate to return the year as a four-digit number.

Also, make sure to import getdate with a lowercase g, not an uppercase G. This is because the date-fns library follows the convention of using lowercase function names rather than the native Date object's uppercase method names.
