Introduction

A common task in cloud computing is data cleaning, which is the process of taking an initial data set that may contain erroneous or incomplete data, and removing or fixing those elements before formatting the data in a suitable manner. In this assignment, you will be tested on your knowledge of JavaScript by implementing a set of functions that perform data cleaning operations on a dataset.

Objectives

By the end of this assignment, you will:

• Gain proficiency in using JavaScript for data manipulation.

• Be able to implement various data cleaning procedures, and understand the significance of them.

• Have developed problem-solving skills through practical application

Problem description
