JavaScript Mastery from Zero to Hero - Prepare for Coding Interviews - Iterate Through Objects with the For…in JavaScrip

The video tutorial explains how to use the for...in statement in JavaScript to iterate over objects. Unlike arrays, objects require the for...in loop to access their enumerable properties, including inherited ones. The tutorial provides an example using a video game character object (NPC) with attributes like character type, weapon, and beard. It demonstrates how to log both keys and values using the for...in loop. The lesson concludes with an exercise for further practice.
