How do get information from .json file-CodePudding

I have this index.js and it's logging the whole .json file. I want to log the age (21). How do I do that?

const fs = require('fs');
 
async function doSomething() {
  const data = fs.readFileSync("./apple.json")
  const data2 = await JSON.parse(data)
  console.log(JSON.stringify(data2, null, 2))
}
doSomething()

and a side question: Is there a way to avoid using fs to read files?

/*
apple.json

{
   "memberList":[
      {
         "age":"21",
         "name":"Jom"
      }
   ]
}
*/

/*
Output:
 
{
  "memberList": [
    {
      "age": "21",
      "name": "Jom"
    }
  ]
}
 
*/

CodePudding user response：

Your first question is quite obvious and this answer will not address it. Regarding your second question, yes. Using commonjs you just have to require the file. Like this:

const data = require('./apple.json');

If you are using ES6 modules, then you have to addd a assert statement. Like this:

import data from './apple.json' assert {type: 'json'};

If this answered your question, then you can mark it as correct.

Did you try to access the members of memberList?

console.log(data2.memberList[0].age);
