Exactly what the doctor ordered! I love it, I feel this avoids the pitfalls and complexities of class-based inheritance
Here you go Adrian-Samuel, this is how to extend the counter with mixins, without having to update the original object...
const Counter = (count = 0) => ({ add: () => (count += 1), get count() { return count; } }); let counter = Counter(0); counter.add(); counter.count; console.log(counter.count); // 1 const subtract = () => ({ subtract() { this.count -= 1; } }); const multiply = () => ({ multiply(amount) { this.count *= amount; } }); const extend = (base, ...mixins) => Object.assign( { ...base }, ...mixins.map(method => method()) ); counter = extend(counter, subtract, multiply); counter.subtract(); counter.subtract(); console.log(counter.count); // -1 counter.multiply(2); console.log(counter.count); // -2
This is superb! Alistair, really appreciate you taking the time and effort to demonstrate these very useful examples to me!
