🚸 Shorter stringified values for null-prototype

[dubzzz]

Description

As specified on MDN Web Doc @ Object # null-prototype objects, there are two main ways to build instances having null-prototype:

However, you may create null-prototype objects using Object.create(null) or the object initializer syntax with proto: null [...]

const obj = Object.create(null);
const obj2 = { __proto__: null };

Up-to-now, fc.stringify has been using the first notation with Object.assign added to it to add keys within the instance. But as Object.create + Object.assign tend to be longer than the ___proto__:null, we swicth to that shorter notation in that PR.

Advanced

• Category: ✨ Introduce new features
• Impacts: Lighter display for prototype-less instances

⚠️ Minor breaking change: As it may slighty impact final users (exposed API), we will wait a major version to release it (major being close, let's wait for it). It seems to be compatible with any version of node, at least from 0.10.48 so the eval(fc.stringify(value)) would still work.
