Syntax:
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
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
const collect = require( 'collect.js' );
let sum = 0;
const collection = collect([1 , 5 , 7 , 9]);
collection.each((item) => {
sum += item;
