javascript - 如何在 JavaScript 中删除对象数组中的重复对象

Question

我想删除重复的对象。我怎样才能做到这一点？

const array1 = [{ currencyName : "USD", code: "121" }, 
                { currencyName : "INR", code: "123" }];

const array2 = [{ currencyName : "USD", code: "121" }];

Result = [{ currencyName : "INR", code: "121" }]

Answer 1

尝试使用filter和一些方法:

const array1 =[ 
    { currencyName : "USD", code: "121" }, 
    { currencyName : "INR", code: "123" }
]

const array2=[ { currencyName : "USD", code: "121" }];

const result = array1.filter(f=> 
    !array2.some(s=> f.code === s.code && f.currencyName === s.currencyName)
);

console.log(result)
