The Modern JavaScript Bootcamp (2019) - Improve Our Expense Tracker

This video tutorial guides learners through building an enhanced version of an expense tracker app. Initially, the app tracked expenses using a single number, but now it uses arrays of objects to store detailed expense data. The tutorial is divided into two challenges: the first involves creating methods to add expenses and summarize accounts, while the second introduces income tracking and account balance calculation. The video emphasizes practical coding exercises and encourages learners to apply JavaScript concepts like objects, arrays, and functions.
