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
}
];
