Benchmark: destructuring vs for-in

Script Preparation code:

var props = {key: 1, ref: () => {}, a: 1, b: "b", children: ["hello world"]};

Tests:

destructuring
const {key, ref, ...props1} = props;
for...in
let key; let ref; const props1 = {}; for (const name in props) { if (name === "key") { key = props[name]; } else if (name === "ref") { ref = props[name]; } else { props1[name] = props[name]; } }
