What Is The History Behind JavaScript's == Vs ===? Have you ever wondered why JavaScript has two different ways to compare values? In this detailed video, we'll explain the history and reasoning behind JavaScript's equality operators. We'll start by discussing what these operators are and how they are used in everyday coding. You'll learn about the origins of the loose equality operator (==) and why it was initially introduced to simplify comparisons by automatically converting types. We’ll explore how this feature made coding more flexible but also led to unexpected results and bugs. Then, we'll explain the development of the strict equality operator (===), which compares both value and type without any conversions. You'll understand why many developers prefer to use the strict operator to write clearer and more predictable code. Whether you're new to JavaScript or looking to improve your coding practices, understanding the differences between these operators is essential for writing reliable scripts.
