Script Preparation code:

window.address1 = [{ 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 }];
window.address2 = [{ childrenIndex: 1 }, { 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 }];

window.serializeAddressJSON = (address) => JSON.stringify(address);
window.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}`;

	}, '');

Tests:

JSON serialize
serializeAddressJSON(window.address1, window.address2)
Reduce serialize
serializeAddressReduce(window.address1, window.address2)
