The Modern JavaScript Bootcamp (2019) - Constant Variables

The video tutorial introduces the concept of using 'const' in JavaScript as an alternative to 'let' for defining variables. It explains the key difference that 'const' variables cannot be reassigned after their initial assignment, unlike 'let' variables. The tutorial also covers how 'const' works with objects, allowing property changes but not reassignment of the object itself. The importance of using 'const' for code readability is highlighted, as it helps indicate which variables are not meant to change. The video concludes with a brief mention of the next topic, arrays, which will be covered in the following section.
