how to use the skiplast function from the rxjs library in javascript

index.tsx
// Import the necessary operators from rxjs
import { from } from 'rxjs';
import { skipLast } from 'rxjs/operators';

// Create an Observable
const nums = from([1, 2, 3, 4, 5]);

// Skip the last 2 values emitted from the Observable
const skipped = nums.pipe(skipLast(2));

// Subscribe to the Observable and log each value emitted
skipped.subscribe(num => console.log(num));
