# `countBy()` The countBy method counts the occurences of values in the collection. By default, the method counts the occurrences of every element: ```js const collection = collect([1, 2, 2, 2, 3]); const counted = collection.countBy(); counted.all(); // { // 1: 1, // 2: 3, // 3: 1, // } ``` However, you pass a callback to the countBy method to count all items by a custom value: ```js const collection = collect([ 'mohamed.salah@gmail.com', 'darwin.nunez@yahoo.com', 'roberto.firmino@gmail.com', ]); const counted = collection.countBy(email => email.split('@')[1]); counted.all(); // { // 'gmail.com': 2, // 'yahoo.com': 1, // } ``` [View source on GitHub](https://github.com/ecrmnn/collect.js/blob/master/src/methods/countBy.js)
