👉 Writable is a technical concept in computer science that refers to an object or data structure that can be written to another object. In other words, it allows you to modify or access the value of an object without modifying its original state. This means that if you write to a writable object, you will not lose any information about the original object's state. It is used in programming languages such as Java and Python to store data and make changes to it without affecting the original object.
