The Modern JavaScript Bootcamp (2019) - Promise Chaining

The video tutorial introduces promise chaining in JavaScript, highlighting its advantages over callbacks, which often lead to 'callback hell' due to complex nesting. The tutorial demonstrates how promise chaining can simplify asynchronous code by maintaining a flat structure, making it easier to read and maintain. It also covers error handling using the 'catch' method, allowing for a single error handler for multiple promises.

What modifications are made to the 'get data promise' function to handle numbers?

How can you avoid deeply nested code when using promises?

In what way does promise chaining allow for the addition of more asynchronous actions?

What is the main goal of using promise chaining as discussed in the text?
