Differences between Object.freeze( ) and Object.seal( ) in Javascript

They are functions that may appear to do the same action but have significant differences. And it was difficult for me to learn it. I don't know why but they always confused me.

Object.freeze(): It prevents you from adding new properties, removing existing properties and modifying them.

Object.seal(): You can modify existing properties but you can't delete or add new ones.

CRUD Operations

If we differentiate them through the CRUD operations: Create - Read - Update - Delete, we obtain the following comparison.

                  Create     Read    Update     DeleteObject.freeze()                           Object.seal()                             

The wonderful world of Javascript. That's all for today :)
