_.intersectionWith([arrays], [comparator]) This method is like _.intersection except that it accepts comparator which is invoked to compare elements of arrays. The order and references of result values are determined by the first array. The comparator is invoked with two arguments: (arrVal, ...

To truly understand the benefits of es-toolkit, let’s compare its performance and bundle size to Lodash. Performance es-toolkit’s functions are often faster than Lodash’s because they use modern JavaScript APIs in their implementations. For example, es-toolkit’somitfunction is about 11.8 times...
[3, 2, 1].sort(_.compareWith(function(a, b) { return a - b; })) Object Manipulation Lodash allows for easy manipulation and traversal of objects. The code sample shows how to assign properties from source objects to a destination object. ...
Lodash xorWith Method - Learn how to use the xorWith method in Lodash, a powerful utility library for JavaScript that simplifies working with arrays and objects.
This method is like _.difference except that it accepts comparator which is invoked to compare elements of array to values. Result values are chosen from the first array. The comparator is invoked with two arguments: (arrVal, othVal). Since 4.0.0 Arguments array (Array): The array to insp...
