When you want to display words, labels, or any kind of readable content on your canvas, Fabric.js provides robust support for text objects. There are two main classes designed for this purpose: fabric.Text and fabric.IText. Both allow you to add text to your canvas, but they serve slightly different roles.

fabric.Text is used for static text. This means users can see the text, and you can style and move it, but it cannot be edited directly on the canvas by the user. It is ideal for labels, titles, or any information that should not be changed interactively.

On the other hand, fabric.IText stands for "interactive text." This class extends the capabilities of fabric.Text by allowing users to click on the text object and edit its content directly on the canvas. This is perfect for applications like graphic editors, meme generators, or any tool where users need to input or modify text on the fly.

Both text types support a wide range of properties for customization. You can change the font family, size, style (bold, italic), color, alignment, and more. You can also apply transformations such as rotation, scaling, and skewing, just like with other Fabric.js objects. The main difference comes down to whether you want your text to be editable by the user or not.
