The code will generate an array of one thousand objects with the properties.

userProfile.js

function userProfiler(howMuch){
  return new Array(howMuch).fill().map((data,i)=>{
      return {
       'id' : i,
       'name' : 'dummyUser'+i,
       'Mobile' : Math.floor(Math.random() * 9000000000) + 1000000000,
       'age' : Math.floor(Math.random() * (100-10 + 10) + 1)
      }
  });
}

console.log(userProfiler(100));
