如何将嵌套数组的对象转换为平面对象数组？

Question

我有一系列选项的对象。在每个选项上，我都需要创建平面对象。就像这样

name: 'win10',
        architectures: ['x64', 'x86'],
        languages: ['en', 'ru'],

转化为：

[
{ name: 'win10',
        architectures 'x64',
        languages: 'en',
}, {
name: 'win10',
        architectures:  'x86',
        languages: 'ru',
}, {
name: 'win10',
        architectures: 'x64',
        languages: 'en',
}, {
name: 'win10',
        architectures: 'x86',
        languages: 'ru',
}
]

Answer 1

这应该可以做到：

let input = {
        name: 'win10',
        architectures: ['x64', 'x86'],
        languages: ['en', 'ru']
};

function flatten(system) {
        let output = [];

        for (let i = 0; i < system.architectures.length; i++) {
                const arch = system.architectures[i];
                for (let j = 0; j < system.languages.length; j++) {
                        const lang = system.languages[j];
                        output = [...output, {
                                name: system.name,
                                architectures: arch,
                                language: lang
                        }];
                }
        }
        return output;
}

const output = flatten(input);

console.log(output);

Answer 2

这是另一种方法

var x = { name: 'win10',
        architectures: ['x64', 'x86'],
        languages: ['en', 'ru'] }
var k = [];
 x.architectures.forEach(p => {
 x.languages.forEach((y => {
    k.push({name: x.name, architectures:p,languages:y})
  }))
})

console.log(k)
