How to Get an Object Keys and Values in JavaScript

Answer:

Javascript object

const MyObj = {
 name: 'RustcodeWeb', 
 mail: 'rustcode95@gmail.com', 
 website: 'www.rustcodeweb.com'
};

First Method

for (var k in MyObj){
 if (MyObj.hasOwnProperty(k)) {
   console.log("Key: " + k + ", value: " + MyObj[k]);
 }
}

Second Method

for (const [key, value] of Object.entries(MyObj)) {
  console.log("Key: " + key + ", value: " + value);
}

Output:

Key: name, value: RustcodeWeb
Key: mail, value: rustcode95@gmail.com
Key: website, value: www.rustcodeweb.com

But if you want to extract 'values' or 'keys' separately, then follow the below method:

extract keys

console.log(Object.keys(MyObj));

Output:

["name", "mail", "website"]

extract values

console.log(Object.values(MyObj));

Output:

["RustcodeWeb", "rustcode95@gmail.com", "www.rustcodeweb.com"]
