假设我们有两个这样的对象-
const obj1 = {
positive: ['happy', 'excited', 'joyful'],
negative: ['depressed', 'sad', 'unhappy']
};
const obj2 = {
happy: 6,
excited: 1,
unhappy: 3
};我们需要编写一个接受两个这样的对象的JavaScript函数。然后,该函数应同时使用这两个对象来计算正负得分,并返回如下对象:
const output = {positive: 7, negative: 3};为此的代码将是-
const obj1 = {
positive: ['happy', 'excited', 'joyful'],
negative: ['depressed', 'sad', 'unhappy']
};
const obj2 = {
happy: 6,
excited: 1,
unhappy: 3
};
const findPositiveNegative = (obj1 = {}, obj2 = {}) => {
const result ={}
for (let key of Object.keys(obj1)) {
result[key] = obj1[key].reduce((acc, value) => {
return acc + (obj2[value] || 0);
}, 0)
};
return result;
};
console.log(findPositiveNegative(obj1, obj2));输出结果
控制台中的输出将是-
{ positive: 7, negative: 3 }
