Lesson 4: JavaScript Variables

• I learned about JavaScript variables as containers for information and the various data types they can hold (strings, numbers, booleans, and objects).
• The importance of declaring variables using `var` and the distinction between local and global variables were clarified.
• I learned about assignment and comparison operators and their uses.
• This lesson provided a solid understanding of variables in JavaScript, and I look forward to applying this knowledge in future lessons.
