Object Freeze v/s Object Seal - JavaScript Features
****************************************************************************
Object. freeze() makes an object immune to everything even little changes cannot be made. Object. seal() prevents from deletion of existing properties but cannot prevent them from external changes.
There is no way to unfreeze , once an object has been frozen there is no way to unfreeze it. This is technically correct as far as mutating the existing object. However, you can copy/clone the existing object and mutate it's properties now.
