The video also touches on variable naming conventions and the importance of using camel case for better code readability.
Highlights
- 💻 *Variables are like storage containers for data.* They allow you to store and manipulate information within your JavaScript code.
- 💡 *There are three main types of variables:* `var`, `let`, and `const`. Each has its own characteristics and use cases.
- 🔐 *`var` variables are globally scoped,* meaning they are accessible from anywhere in your code, while `let` variables are block-scoped, limiting their accessibility.
- 🔒 *`const` variables are constant,* meaning their value cannot be changed after initialisation.
- 🐪 *Following camel case convention* for variable naming makes your code more readable and maintainable.
