Lodash _.dropRight


The lodash _.dropRight method returns an array with n elements dropped from the end, where n is the number of elements to drop. This method does not modify the original array, but instead returns a new array.

The syntax for using _.dropRight is as follows:

_.dropRight(array, [n=1])

Here, array is the array to modify, and n is the number of elements to drop from the end of the array. By default, n is set to 1.

For example, given the following array:

var arr = [1, 2, 3, 4, 5];

We can drop the last two elements using _.dropRight:

_.dropRight(arr, 2);
// output: [1, 2, 3]

If no second argument is provided, _.dropRight will drop the last element of the array:

// output: [1, 2, 3, 4]

_.dropRight can also be used with objects with a length property:

var obj = { 'length': 3, '0': 'a', '1': 'b', '2': 'c' };
// output: ['a', 'b']

Finally, _.dropRight can receive a predicate function that decides which elements to drop from the array:

var arr = [1, 2, 3, 4, 5];
_.dropRight(arr, function(n) {
  return n > 2;
// output: [1, 2]

In this example, _.dropRight will drop any elements from arr that are greater than 2.
