JS - Convert multi-dim array that has been JSON.stringify to a string back to a JS multidim array

file.js

//
// Take a string like '{"title":"An event","start":"2023-05-01"},{"title":"Another event","start":"2023-05-15"},{"title":"Yet another event","start":"2023-05-24"}'
//  and convert it back into a multidim array


var string_vers = JSON.stringify(original_array);

var reconstructed = reconstruct_multi_dim( string_vers );

console.log( JSON.stringify(reconstructed) );


function reconstruct_multi_dim ( events ) {
	var multi_dim = [];
	var pieces = events.split('},{');
	for (var idx=0; idx < pieces.length; idx++) {
		// Fix up the formatting of the individual JSON stringified arrays
		pieces[idx] = '{'+pieces[idx]+'}';
		pieces[idx] = pieces[idx].replace("{{", "{");
		pieces[idx] = pieces[idx].replace("}}", "}");

		var new_bit = JSON.parse(pieces[idx]);
		multi_dim = multi_dim.concat( new_bit );
	}

	return multi_dim;
