When working with multiple shapes or objects on your canvas, you often need to move, scale, or transform them together. Fabric.js provides a powerful feature for this: groups. The fabric.Group class lets you combine several objects into one logical unit, so you can manipulate them all at once.

To create a group, you simply pass an array of objects to the fabric.Group constructor. For example, if you have a rectangle, a circle, and a triangle, you can group them like this: new fabric.Group([rect, circle, triangle], options). Once grouped, you can add the group to the canvas just like any other object. The group can be selected, moved, scaled, or rotated, and all its child objects will respond together. This makes it much easier to manage complex designs or composite shapes, since you do not have to update each object individually.

Grouping is especially helpful when you want to treat several objects as a single entity for user interactions. You can always ungroup later if you need to work with the individual elements again.
