Question
ES6 Iterate over array and find corresponding item in a different object
Solution
To iterate over an array and find the corresponding item in a different object using ES6, you can follow these steps:
-
First, create an array that you want to iterate over. Let's call it
arrayToIterate. -
Next, create an object that you want to find the corresponding item in. Let's call it
objectToSearch. -
Use the
forEachmethod to iterate over each item in thearrayToIterate. Inside theforEachloop, you can access each item using the parameter of the callback function.arrayToIterate.forEach(item => { // Your code here }); -
Inside the
forEachloop, you can use thefindmethod on theobjectToSearchto find the corresponding item based on a condition. Thefindmethod returns the first item that satisfies the condition.const correspondingItem = objectToSearch.find(obj => { // Your condition here });Note: In the condition, you can compare the properties of the
itemfromarrayToIteratewith the properties of the objects inobjectToSearchto find the corresponding item. -
You can then perform any desired operations with the
correspondingItemfound.
Here's an example that demonstrates the above steps:
const arrayToIterate = [1, 2, 3, 4, 5];
const objectToSearch = [
{ id: 1, name: 'Apple' },
{ id: 2, name: 'Banana' },
{ id: 3, name: 'Orange' },
{ id: 4, name: 'Grapes' },
{ id: 5, name: 'Mango' }
];
arrayToIterate.forEach(item => {
const correspondingItem = objectToSearch.find(obj => obj.id === item);
console.log(correspondingItem);
});
In this example, we iterate over each item in arrayToIterate and find the corresponding item in objectToSearch based on the id property. The corresponding item is then logged to the console.

Iterating Array With Different Data Types
How do you access elements in an array?
Use the map function to create objects from the arrays.The mapping should be done in such a way that for the first object, the first element of all arrays should be used, and so on.Input:const ids = [1, 2, 3];const names = ["John", "Jane", "Alice"];const images = ["john.jpg", "jane.jpg", "alice.jpg"];createUserObjects(ids,names,images);Output:[ { id: 1, name: 'John', image: 'john.jpg' }, { id: 2, name: 'Jane', image: 'jane.jpg' }, { id: 3, name: 'Alice', image: 'alice.jpg' }]
Create a function getListStudentIds that returns an array of ids from a list of object.This function is taking one argument which is an array of objects - and this array is the same format as getListStudents from the previous task.If the argument is not an array, the function is returning an empty array.You must use the map function on the array.bob@dylan:~$ cat 1-main.jsimport getListStudentIds from "./1-get_list_student_ids.js";import getListStudents from "./0-get_list_students.js";console.log(getListStudentIds("hello"));console.log(getListStudentIds(getListStudents()));bob@dylan:~$ bob@dylan:~$ npm run dev 1-main.js [][ 1, 2, 5 ]bob@dylan:~$
