如何使用另一个的值覆盖一个Object(lodash)

我正在寻找一个函数,如果它存在,覆盖一个对象的值与另一个对象的值,但我没有在lodash文档中找到它

var primary = {
    name: 'egg'
    weight: '2oz',
    meal: 'breakfast'
}
var secondary = {
    name: 'egg',
    weight: '3oz'
    state: 'uncracked'
}

var result = _.override(primary, secondary);

console.log(result)
// => { name: 'egg' weight: '3oz', meal: 'breakfast, state: 'uncracked' }

如何在函数式编程中实现这一目标？

Checkout Lodash的_.assign功能 - https://lodash.com/docs/4.17.2#assign.

Note: This method mutates object and is loosely based on Object.assign.

var primary = {
    name: 'egg',
    weight: '2oz',
    meal: 'breakfast'
};

var secondary = {
    name: 'egg',
    weight: '3oz',
    state: 'uncracked'
};

var result = _.assign({}, primary, secondary);

console.log(result)
// => { name: 'egg' weight: '3oz', meal: 'breakfast, state: 'uncracked' }
