Description
__proto__ property has been deprecated as of ECMAScript 3.1 and shouldn't be used.
Use Object.getPrototypeOf and Object.setPrototypeOf instead.
Bad Practice
let objProto = obj.__proto__;
objProto = obj["__proto__"];
obj.__proto__ = proto;
obj["__proto__"] = proto;
Recommended
const proto = Object.getPrototypeOf(obj);
Object.setPrototypeOf(obj, proto);
