Answer 1

jia1 = [{
    x: [1, 2, 3, 4],
    y: [11, 22, 33, 44]
}, {
    x: [9, 8, 37, 16],
    y: [99, 88, 23, 13]
},
    {
        x: [6, 3, 1, 6],
        y: [3, 1, 8, 9]
    }]
let numMap = {1: 'one', 2: 'two', 3: 'three'};
jia1.map((item, index) =>
    ({name: numMap[index + 1], data: item.x.map((n, i) => [n, item.y[i]])}))
