In web development, variables are essential for storing and manipulating data. Think of them as labeled containers that hold information like names, numbers, or text. We use them to make our websites dynamic and interactive. Variables have a name (identifier) and a value. The value can change as the user interacts with the website or as the code runs. In the context of web basics, understanding variables is the foundation for creating more complex and responsive web applications. They allow us to store information temporarily and perform operations on it, making websites more engaging and user-friendly.
