Get/Set
const obj = { __value: 0, get value() { return this.__value; }, set value(v) { this.__value = v; } }; function increase() { obj.value = obj.value + 1; } while (obj.value < 1000) { increase(); }
Function
const obj = { __value: 0, getValue() { return this.__value; }, setValue(v) { this.__value = v; } }; function increase() { obj.setValue(obj.getValue() + 1); } while (obj.getValue() < 1000) { increase(); }
Proxy
const obj = new Proxy( { value: 0 }, { get(obj, key) { return obj[key] }, set(obj, key, value) { obj[key] = value }, } ); function increase() { obj.value = obj.value + 1; } while (obj.value < 1000) { increase(); }
