Understanding the difference between Map and ForEach method
Let’s switch gears to a scenario where you need to update each element of an array. Consider an array of user objects, and you want to mark all users above a certain age as “verified.” Here’s where the forEach method plays its role:
const users = [
{ name: 'Alice', age: 28, verified: false },
{ name: 'Bob', age: 35, verified: false },
{ name: 'Eve', age: 22, verified: false }
];
users.forEach(user => {
if (user.age > 30) {
user.verified = true;
}
});
In this case, the forEach method iterates through each user object and updates the verified property for users above the age of 30.
