在reactjs中需要一些幫助我下面有這些數(shù)據(jù)，我想顯示它而不重復(fù)，這意味著它應(yīng)該是“A”、“B”和“D”的單個(gè)類別，我想在下面的地圖中執(zhí)行此操作。 const person = {   con: [    { category: "A", name: "john"  },    { category: "A", name: "john" },    { category: "B", name: "rahul" },    { category: "B", name: "jay" },    { category: "C", name: "dave" },    { category: "D", name: "alex" },    { category: "D", name: "alex" },    { category: "E", name: "sam1" },    { category: "F", name: "sam2" },    { category: "G", name: "sam3" },   ] };person.con && person.con.map((data, index) => (   console.log(data, 'data')     // I want to display results here... ))預(yù)期輸出：{ category: "A", name: "john"  },{ category: "B", name: "rahul" },{ category: "C", name: "dave" },{ category: "D", name: "alex" },{ category: "E", name: "sam1" },{ category: "F", name: "sam2" },{ category: "G", name: "sam3" },這可能嗎？謝謝。
