How to conditionally build an javascript object with features in

Exploring the processing of RSS feeds for podcasts using command-line interfaces, Express, and Serverless functions, the text discusses handling user-generated data with varying field presence by employing modern JavaScript (ES6) features. Initially, the process involved conditional application of new keys to objects, but this approach was cumbersome and lacked clarity. The author then transitions to a more concise and efficient method using parameter object destructuring and the spread syntax, which facilitates cleaner and more testable code. This approach is demonstrated in a function that parses episode data, illustrating the streamlined handling of optional fields and the benefits of incorporating ES6 syntax in practical applications such as podcast feeds implemented with express.js and Netlify lambdas.
