how to use the droprightwhile function from lodash in javascript

To use the droprightwhile function from lodash library, you need to first install lodash using either npm or yarn. Once you have lodash installed and imported into your file, you can use the droprightwhile function to iterate through an array from right to left and drop elements until the iterator function returns false.

Here is an example code snippet that will remove all elements from an array from the right end until the element's value is less than 4:

index.tsx
const _ = require('lodash');

const array = [5, 8, 2, 2, 1, 3, 7];

const result = _.droprightwhile(array, (value) => {
  return value >= 4;
});

console.log(result); // Output: [5, 8, 2, 2]
191 chars
10 lines

In the above code, the droprightwhile function receives the array as the first argument and the second argument is an iterator function that checks each element's value from right to left. The iteration stops as soon as the iterator function returns false for any element of the array.

The result variable will hold the final array returned by the droprightwhile function. It will return an array that consists of all the elements from the original array up until the one that failed the iterator function.

Note that the lodash library provides a lot of utility methods to work with arrays and objects in JavaScript, and droprightwhile is just one of them.
