如何从元素数组 return 到新数组？

Question

我有一个元素数组，我想用一个键作为名称映射到一个新的对象数组。

let array = ["abc", "def", "xyx"]

预期输出

let array1 = [{name: "abc"}, {name: "def"}, {name: "xyz"}]

Answer 1

您可以使用 array.map:

let newArray = array1.map((value) => ({name: value});

Answer 2

let arr = ['a', 'b', 'c'];

let newArr = arr.map(el => ({ name: el }));

console.log(newArr);

Answer 3

你可以使用 map() 函数，

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map

    let array = ["abc", "def", "xyx"]
    const array1 = array.map( data => { 
    return {name:data}
    })
    /* this code will also work,if you dint specify the properties name 
    by default it will be the variable's name. In this case 'name' */
     const array2 = array.map( name => { 
    return {name}
    })
    console.log(array1)
    console.log(array2)
