Cleaning and Preparing Data
We rely on data to answer important questions, whether we are trying to make the best business decisions or determine the effectiveness of a new medical treatment. But our analyses are only as accurate as the data we are using, and incorrect or “dirty” data can lead to incorrect conclusions and assumptions. Data preparation, also called “cleaning” or “scrubbing”, is an important part of ensuring our analyses are accurate and useful.

Introduction to Software Testing
Learn how to become an effective test engineer. Testing is something every developer must do to write effective and quality code, but going about what you should test and how to do it can be a challenging question. Quality Assurance is the practice of monitoring other developers' work and creating processes and tests that will ensure the product meets the end user’s expectations and limiting the amount of bugs that are released. This course will teach you how to become a Software Quality Assurance Engineer.

UX Content Strategy
With so many websites and apps offering similar content and features, you need to provide a unique experience to compete - something memorable and enjoyable that resonates with your users.

Workshop
React Context API
In the typical React data flow, components communicate with each other via props. A parent passes props down to child components. Sometimes the intermediary components get props passed to them with the sole purpose of passing that data down one (or several) more levels deep. This cascade of props is often referred to as "prop drilling". The React Context API provides a way to pass data to components without having to pass props manually at every single level.
