The Modern JavaScript Bootcamp (2019) - Booleans and Comparison Operators

This video tutorial introduces the concept of conditional logic in programming, focusing on the use of Booleans in JavaScript. It explains how Booleans are used to represent true or false values and introduces comparison operators to generate Booleans based on conditions. The tutorial includes practical examples and a challenge to apply these concepts in a real-world scenario, such as determining age-based discounts.
