如何使用JavaScript从Map Object获取密钥

Question

I have this structure below:

/* Wrapper to format cellphone configuration list for selectors. */
    function buildConfiguration(){
        return {
            "Item 1": {
                name: {
                    "aaa": 1,
                },
                blue: {
                },
                green: {
                },
                black: {
                },
                yellow: {
                }
            },

            "item 2": {
                name: {
                    "aaa 5": 1,
                    "bbb 6": 2,
                    "ccc 7": 3
                },
                blue: {
               },
                green: {
               },
               black: {
               },
               yellow: {
               }
           }
       }
   } 

I would like get the keys from this map object.

I'm trying this console.log(Object.keys(buildConfiguration));

but return 0 itens.

Could please help me?

You need to call that function like buildConfiguration() and you're done

 function buildConfiguration(){ return { "Item 1": { name: { "aaa": 1, }, blue: { }, green: { }, black: { }, yellow: { } }, "item 2": { name: { "aaa 5": 1, "bbb 6": 2, "ccc 7": 3 }, blue: { }, green: { }, black: { }, yellow: { } } } } console.log(Object.keys(buildConfiguration()))
