Javascript json data grouping

Sorry if this has been asked before, but I couldn't find a good example of what I'm trying to accomplish. Maybe I'm just not searching for the right thing. Please correct me if there's an explanation of this somewhere. Anyway...
抱歉，如果之前有人问过这个问题，但我找不到我想要完成的工作的好例子。也许我只是没有在寻找正确的东西。如果在某处对此有解释，请纠正我。反正...

{"Level":"3A","TeamName":"Team 4","League":"League 1"},
{"Level":"3A","TeamName":"Team 5","League":"League 2"},

How would I accomplish this with Javascript/jQuery? Unfortunately I can't edit what the server is sending me.
我将如何使用 Javascript/jQuery 完成此操作？不幸的是，我无法编辑服务器发送给我的内容。

Just keep track of it all in an object:
只需在一个对象中跟踪所有内容：
let groups = Object.create(null);
data.forEach(item => {
if (!groups[item.Level]) {
groups[item.Level] = [];
}
groups[item.Level].push({
TeamName: item.TeamName,
League: item.League
});
});
let result =
Object.entries(groups)
.map(([k, v]) => ({[k]: v}));
