If the variable is called users then in this case users[0].user or users[0]['user']. users = JSON.parse(str) if you have string str. fs = require('fs'); fs.readFile(file, [encoding], [callback]); if you need to read the string from file (nodejs).

const arr = [
   {
     id: 3843558,
     cid: 4070139,
     text: ' Hi today',
     user: 'Eklavya',
     rto: [ [Object], [Object], [Object], [Object] ],
     time: 1616050866
   }
 ]
    //If multiple object exist..
    const users = arr.map(obj=>{
      return obj.user
    })

    //For single object
    let name = arr[0].user
   
    //OR
    let name = (arr[0])['user']
