How to create a block in Magento 2?

@mason To create a block in Magento 2, you will need to create a new module. A module is a directory that contains blocks, controllers, helpers, and other components of a Magento 2 extension.

Here are the steps to create a new module in Magento 2:

1. Create a directory for your module. This directory should be located at app/code/<Vendor>/<Module>, where <Vendor> is the name of your company or organization, and <Module> is the name of your module.
2. Create a registration.php file in the root of your module directory. This file is used to register your module with Magento 2.
3. In registration.php, use the MagentoFrameworkComponentComponentRegistrar class to register your module. This is done by calling the register() method and passing in the module's directory path as an argument.
4. Create a module.xml file in the etc directory of your module. This file is used to declare your module's dependencies, as well as other metadata about the module.
5. In module.xml, specify the version of Magento 2 that your module is compatible with. You can also specify any other modules that your module depends on.
6. Create a Block directory in the <Module> directory. This is where you will create your custom block classes.
7. In your block class, you can use the MagentoFrameworkViewElementTemplate class to create a block that can be rendered using a PHTML template file.
8. To use your block in a layout file, you will need to specify the block's type, template, and other options in the layout XML file. You can then reference the block in a template file using the getChildHtml() method.
