How to display object key and value in JavaScript?

There are several ways to achieve this in JavaScript, but the most common method is by using a for…in loop to iterate through the object and display the key-value pairs. Here’s how you can do it:

“`javascript
const obj = {
key1: ‘value1’,
key2: ‘value2’,
key3: ‘value3’
};

for (let key in obj) {
console.log(`${key}: ${obj[key]}`);
}
“`

This code snippet will output:

“`
key1: value1
key2: value2
key3: value3
“`

By using a for…in loop, you can easily access the keys and values of an object in JavaScript.

How can I check if an object is empty before trying to display its key and value?
