When working with objects in Fabric.js, you often need to control their orientation for layout or design purposes. The angle property allows you to specify a custom rotation for any object on the canvas. This property determines how much the object is rotated around its center point.

To set a custom rotation, assign a numerical value to the angle property of an object. This value represents the rotation in degrees, not radians. Positive values rotate the object clockwise, while negative values rotate it counterclockwise. You can set the angle when you create the object or update it later by assigning a new value to the angle property. Adjusting the angle property is especially useful for aligning shapes, creating dynamic layouts, or adding visual interest to your design.
