Benchmark: Reduce deserialize vs JSON deserialize

Script Preparation code:

const address_raw = [{ childrenIndex: 0 }, { toggleIndex: 1 }, { instanceIndex: 2 }, { childrenIndex: 0 }, { toggleIndex: 1 }, { instanceIndex: 2 }, { childrenIndex: 0 }, { toggleIndex: 1 }, { instanceIndex: 2 }, { childrenIndex: 0 }, { toggleIndex: 1 }, { instanceIndex: 2 }, { childrenIndex: 0 }, { toggleIndex: 1 }, { instanceIndex: 2 }];

const serializeAddressJSON = (address) => JSON.stringify(address);
const serializeAddressReduce = (address) =>
	address.reduce((serialized, point) => {
		const { childrenIndex, toggleIndex, instanceIndex } = point;

		let pointCode;
		if (childrenIndex !== undefined) {
			pointCode = `c${childrenIndex}`;
		}
		if (toggleIndex !== undefined) {
			pointCode = `t${toggleIndex}`;
		}
		if (instanceIndex !== undefined) {
			pointCode = `i${instanceIndex}`;
		}

		return `${serialized}${pointCode}`;
	}, '');

window.addressJSON = serializeAddressJSON(address_raw);
window.addressReduce = serializeAddressReduce(address_raw);

window.deserializeAddressJSON = (address) => JSON.parse(address);

window.deserializeAddressReduce = (serializedAddress) => {
	const pointCodeRegex = /([cti])(\d+)/g;
	const addressPointsMatches = serializedAddress.matchAll(pointCodeRegex);
	const address = [...addressPointsMatches].map(([_match, pointType, index]) => {
		switch (pointType) {
			case 'c':
				return { childrenIndex: +index };
			case 't':
				return { toggleIndex: +index };
			case 'i':
				return { instanceIndex: +index };
		}
	});
	return address;
};
