Does JavaScript's Const Keyword Make Variables Truly Immutable? Have you ever wondered how the const keyword works in JavaScript and what it really means for your code? In this informative video, we'll explain everything you need to know about using const to declare variables in JavaScript. We'll start by defining what the const keyword does and how it differs from other variable declarations like let and var. You'll learn how const affects variable reassignment and what it means for primitive data types such as numbers and strings. We will also explore how const interacts with objects and arrays, including what you can and cannot do with reference types declared as const. Additionally, we'll discuss methods like Object.freeze and their role in making objects and arrays truly unchangeable, especially when dealing with nested data structures. Whether you're a beginner or an experienced developer, understanding the nuances of const helps you write clearer, more predictable code. This knowledge is especially useful when working with frameworks like React or managing complex data.
