In Node.js, you can remove a property or key from an object using the `delete` keyword.

Here's an example:

const myObj = {
  name: 'John',
  age: 30,
  city: 'New York'
};

delete myObj.city;

console.log(myObj);
// Output: { name: 'John', age: 30 }

In this example, we create an object `myObj` with three properties: `name`, `age`, and `city`. We then use the `delete` keyword to remove the `city` property from the object. Finally, we log the object to the console to verify that the `city` property has been removed.

To remove string duplicates from an array in Node.js, you can use the `filter` method along with the `indexOf` method.

Here's an example:

Cheerio is a very popular tool for parsing HTML and XML in NodeJs. It is fast, flexible, and easy to use. Since it implements a subset of JQuery, it's easy to start using Cheerio if you're already familiar with JQuery.

Here is how to search for HTML code with Cheerio in NodeJs.

Searching by elements

To search for particular HTML code using Cheerio in Node.js, you can use the $ function to load the HTML string or file and then use CSS selectors to find the desired element or elements.

In Node.js, you can check if an object is empty by using the Object.keys() method to get an array of the object's keys, and then checking the length of the array.

Here's an example:

const obj = {};

if (Object.keys(obj).length === 0) {
  console.log('Object is empty');
} else {
  console.log('Object is not empty');
}

In the above code, Object.keys(obj) returns an empty array because the obj object has no keys. So Object.keys(obj).length will be 0, indicating that the object is empty.

Social media has become extremely popular because it allows people to connect in the online world to form relationships for personal and business purposes.

Social media is also called user-generated content (UGC) or consumer-generated media (CGM).

While the previous case studies and numbers prove that social media can help organizations big and small, the next big question is how to apply it specifically to your organization.
