The video tutorial covers assignment operators, focusing on OR, AND, and nullish coalescing operators. It explains how these operators work with falsy and truthy values, providing examples for each. The OR assignment operator is highlighted as particularly useful for setting default values when a variable is falsy. The AND assignment operator is less commonly used but assigns values when a variable is truthy. The nullish coalescing operator is used to assign values only when a variable is null or undefined, avoiding issues with other falsy values like zero or empty strings.
