如何从 Node.js 中的 function 访问 Cloud Function 的返回值 Map？

Question

I had read this post How to return values in javascript . But my question is how do we get the Map value if we derived it from asynchronous function like in this code below:

 async function exampleToken(profile) { let response; const tkAdmin = { admin: true, }; const tkInvestors = { investor: true, }; if (profile == 1) { response = { "token": tkAdmin, "code": 1, }; } else if (profile == 2) { response = { "token": tkInvestors, "code": 2, }; } return Promise.resolve(response); }

I want to use the value from this function using this code:

 const response = await exampleToken(profile); // Is this correct: const code = response.code; const token = response.token; // or const code = response["code"]; const token = response["token"];

Please, help me out. Any tips and trick will be great. Thank you very much for spending time to read this post.

Answer 1

Both are correct in Javascript,

• 1- Dot property accessor: object. property.
• 2- Square brackets property access: object['property']
• 3- Object destructuring: const { property } = object.

This style is named Object Dot Notation access

const code = response.code;
const token = response.token;

and this one is Object Bracket notation access

const code = response["code"];
const token = response["token"];
