用对象迭代数组并删除一个额外的字段[重复]

你好。例如，有一个数组`

testArray = [
        {
            name: 'Salmon - Canned',
            price: '$91.56',
        },
        {
            name: 'Soup - Beef, Base Mix',
            price: '$126.14',
        },
        {
            name: 'Soup - Beef, Base Mix3',
            price: '$126.14',
        },
        {
            name: 'Soup - Beef, Base Mix2',
            price: '$126.14',
        },
    ];

我需要得到一个没有“价格”字段的数组。像这样：

    testArray = [
    {
        name: 'Salmon - Canned',
    },
    {
        name: 'Soup - Beef, Base Mix',
    },
    {
        name: 'Soup - Beef, Base Mix3',
    },
    {
        name: 'Soup - Beef, Base Mix2',
    },
];

怎么做？

    所以？

    let testArray = [
        {
            name: 'Salmon - Canned',
            price: '$91.56',
        },
        {
            name: 'Soup - Beef, Base Mix',
            price: '$126.14',
        },
        {
            name: 'Soup - Beef, Base Mix3',
            price: '$126.14',
        },
        {
            name: 'Soup - Beef, Base Mix2',
            price: '$126.14',
        },
    ];
    
testArray = testArray.map(e => Object.create({name: e.name}));

console.log(testArray);
