Magento 2 Registry & Register: How to Use?

Magento 2 registry is the next topic Mageplaza wants to introduce in the series of this module development. Both Magento 1 and Magento 2 authorize you to register global variable that supports the static registry method.

To implement that, maybe you used to work with Mage::register() and Mage::registry() in Magento 1, but now in Magento 2 platform, there is a difference in running the registry. You will be required to apply \Magento\Framework\Registry, that accepts the settings and the registry of the restored data. However, first of all, you need to learn how to create or use the own custom registry. This article also shows you how to retrieve global Magento 2 registry objects like current product, category, cms page, cms block, etc.

And that is lucky because all of them will be referred here. The topic today will help you be familiar with Magento 2 registry objects.
