Bound property

Imagine you have a toy ball that is attached to a string. When you hold onto the string and pull it one way, the ball moves with it because it is attached and bound to the string.

Now, in computer programming, a bound property is similar. It means that a certain value (like a number or text) is connected, or "bound," to a certain property in your program. If you change the value of the property, the value of the bound property will automatically change too, just like the ball moves when you pull the string.

For example, imagine you have a website where people can choose the background color of a page. You might use a bound property to connect the value of the color picker (the value the user selects) to the background color property of the webpage. Whenever the user chooses a new color, the background color property will also change to match it, without you having to manually change it yourself.
