Summary
During this hour, you've focused on variables and how JavaScript handles them. You've learned how to name variables, how to declare them, and the differences between local and global variables. You also explored the data types supported by JavaScript and how to convert between them.
You also learned about JavaScript's more complex variables, strings and arrays, and looked at the features that enable you to perform operations on them, such as converting strings to uppercase or sorting arrays.
In the next hour, you'll continue your JavaScript education by learning more about two additional key features: functions and objects.
