How to useLodash _.forEach() in Javascript
The _.forEach() method iterates over elements of collection and invokes iteratee for each element.
Step to install:
npm i --save lodash
Example: This example shows the implementation of the above-explained approach.
const _ = require('lodash'); // or, use lodash
const Teacher = [
{ name: 'Marry', age: 23 },
{ name: 'Sam', age: 20 },
{ name: 'Julie', age: 18 }
];
_.forEach(Teacher, (value, _) => console.log(value));
Output:
{ name: 'Marry', age: 23 }
{ name: 'Sam', age: 20 }
{ name: 'Julie', age: 18 }
How to loop through an array containing multiple objects and access their properties in JavaScript ?
Looping through an array of elements is straightforward because you can access them using their indexes. However, it’s a bit different with objects since they consist of key-value pairs, and you can’t index them like an array.
To loop through an array of objects in JavaScript, you need to use different methods compared to traditional arrays. JavaScript provides methods like Object.keys(), Object.values(), and Object.entries() to help you access keys and values of objects easily. These methods make it simpler to work with objects and iterate through their properties.
There are many ways to loop through the array of objects. Let’s look at them one by one:
