How does lodash.pullAll work?

lodash.pullAll works by taking an array and a set of values as input and removing all instances of the values from the array.

The function iterates over the input array and removes any elements that match any of the input values using strict equality (===).

lodash.pullAll modifies the input array in place and returns the modified array.

For example, if the input array is [1, 2, 3, 4, 5] and the values to remove are [2, 3], then the resulting array will be [1, 4, 5].

By using lodash.pullAll, developers can easily remove a set of values from an array without the need for writing repetitive filtering logic.

let pull1 = _.pull(pullArr, 'a', 'c');
console.log('pull1--->', pull1);
//pull1---> [ 'b', 'b' ]


//_.pullAll(array,values)
let pullAll1 = _.pullAll(pullArr, ['a', 'c']);
console.log('pullAll1--->', pullAll1);
//pullAll1---> [ 'b', 'b' ]


//_.pullAllBy(array,values,[iteratee=_.identity])

const _ = require("lodash");

const array = [1, 2, 3, 4, 5];
const values = [2, 3];

const result = _.pullAll(array, values);

console.log(result); // [1, 4, 5]

In this example, we use lodash.pullAll to remove a set of values from an array. We first define an input array array containing five elements and a set of values to remove values containing two elements. We then pass the array and values to _.pullAll() to remove all instances of the values from the array. The function returns the modified array, which is then logged to the console. By using lodash.pullAll in this way, we can easily remove a set of values from an array without the need for writing repetitive filtering logic.
