小白，请教各位大佬！如何把数组內 特定元素放到第一个求指导！

Question

假设有一个数组是这样varqq=[{"group":100,"info":{"event":123},"main":true,},{"group":100,"info":{"event":323},"main":true,"sp":1},{"group":103,"info":{"event":123},"main":true,"sp":13,},{"group":103,"info":{"event":323},"main":true,"sp":10},{"group":103,"info":{"event":123},"main":true,"sp":1}];group是同数字表示是一组的，我想把sp是1的，都放到同组的第一个，并且把main改成false，这具体该怎么实现？有大神可以帮我试试吗最终结果要是这样varqq=[{"group":100,"info":{"event":323},"main":false,"sp":1},{"group":100,"info":{"event":123},"main":true,},{"group":103,"info":{"event":123},"main":false,"sp":1},{"group":103,"info":{"event":123},"main":true,"sp":13,},{"group":103,"info":{"event":323},"main":true,"sp":10}];
