data.each(item)
Parameters: This function accept a single parameter as mentioned above and described below:
- item: This parameter holds the collection item where any operation will be performed on the collection on items.
Return Type: Return a result after performing the define operator operation.
Below examples illustrate the each() function in collect.js
Example 1: Here in this example, we take a collection and then using the each() method , we apply + operation to the collection.
Javascript
// It is used to import collect.js library const collect = require('collect.js'); const num = [0 , 1 , 2 , 3 , 4]; let x = 0; const data = collect(num); data.each((item) => { x += item; }); console.log(`sum = ${x}`); |
Output:
sum = 10
Example 2:
Javascript
// It is used to import collect.js library const collect = require('collect.js'); let sum = 0; const collection = collect([1 , 5 , 7 , 9]); collection.each((item) => { sum += item; }); console.log(sum); |
