重构 Object.keys(object).map 以获取嵌套数组值。 JavaScript

Question

I'd like to refactor a block of code which basically has to map 2 levels to the data I want. The data I want is the value of body in a object that contains ['key'] that has array of objects.

My object looks as follows,

const object = {
    "array-one": [
        {
            id: 1,
            body: "need_help",
      
        },
        {
            id: 2,
            body: "no_help",

        },
    ],
}

and below is how I map to get the value of body

const getTheBodyValue = () => Object.keys(object).map(key => {

    object[key].map((elem) => {
        const { id, body } = elem;
        if (body === 'need_help') // do something
        if (body === 'no_help')  // do something
    });
});

is there a more simpler way to achieve the value of body in "array-one" & "array-two"?

Answer 1

You could flat the values from the object and take a single loop.

Object 
    .values(object)
    .flat()
    .forEach(({ id, body }) => {
        // your code
    })
