Modern JavaScript from the Beginning - Second Edition - Switches

The video tutorial explains how to create a new date in JavaScript and extract the month using the getMonth method. It then introduces switch statements, demonstrating how to evaluate month values and implement range conditions. The tutorial discusses the use cases for switch statements, highlighting their application in scenarios with multiple conditions. The video concludes with a brief mention of their use in front-end frameworks and state management.
