How to useObject.entries() in Javascript

Q: How to useObject.entries() in Javascript

This approach uses the Object.keys() method to get an array of all the keys in the object. It then uses the forEach() method to iterate over each key in the array and access its corresponding value. This approach is useful when you want to perform a specific action for each key in the object.

Approach 2: Using Object.keys()

Approach 4: Using Object.Values()

This approach uses the Object.entries() method to get an array of all the key-value pairs in the object. It then uses the forEach() method to iterate over each key-value pair and access the value, which could be an object. This approach is useful when you want to perform a specific action for each key-value pair in the object.

Syntax:

// Object.entries()
Object.entries(object).forEach(function([key, value]) {
    // do something with value (which could be an object)
});

Example: Using Object.entries() to iterate over an object with objects as members.

Javascript

let person = {
    name: "John",
    age: 30,
    address: {
        street: "123 Main St",
        city: "Anytown",
        state: "CA",
        zip: "12345"
    }
};
Object.entries(person).forEach(([key, value]) => {
    console.log(key + ": " + value);
});

Output

name: John
age: 30
address: [object Object]
