The video tutorial introduces logical operators, focusing on the AND and OR operators, and their practical applications. It explains how the AND operator requires all conditions to be true, while the OR operator needs only one true condition. The tutorial also covers the nullish coalescing operator, which returns the right operand if the left is null or undefined. Practical examples, including handling posts from a database, demonstrate these concepts in action.
