我有一个表格中的数组:
var a1 = [
['AA', 1],
['AA', 2],
['AA', 3],
['BB', 7],
['BB', 8],
['BB', 9]
];
我想将其转换为:
output = [
['AA':1,2,3],
['BB':7,8,9]
]
我需要以这种方式对其进行转换,以便将来自SQL的JSON格式数据放入一个似乎需要数组序列的高图图形中,如下所示 https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/demo/streamgraph/

尝试这样的事情
var a1 = [
['AA', 1],
['AA', 2],
['AA', 3],
['BB', 7],
['BB', 8],
['BB', 9]
];
function generateObj(array) {
const obj = {}
array.forEach(entry => {
obj[entry[0]] = obj[entry[0]] || []
obj[entry[0]].push(entry[1])
})
return obj
}
console.log(generateObj(a1))
