Hint
Proxy get trap intercepts all property reads. Use it for default values, validation, or virtual properties.
const handler = {
get(target, prop) {
return prop in target ? target[prop] : prop + ' not found';
}
};
const obj = new Proxy({ x: 1, y: 2 }, handler);
console.log(obj.x);
console.log(obj.z);1 z not found
Explanation: The get trap intercepts ALL property access. x exists → returns 1. z missing → returns "z not found".
Key Insight: Proxy get trap intercepts all property reads. Use it for default values, validation, or virtual properties.
