How to get only particular object property with values from an json array in javascript

July 19, 2023

I am trying to get some particular property with value from an array object.But it is not working.How to resolve this issue?

var arr1 = [
  {
   name: 'john',
   team: [12, 23, 34],
   sid: 1023,
   options:{boolean:true}
  },
  {
    name: 'john',
    team: [152, 233, 354],
    sid: 1024,
    options:{boolean:true}
   },
  {
   name: 'john',
   team: [152, 273, 314],
   sid: 1025,
   options:{boolean:true}
  },
  ];


 const filteredResult = arr1.find((e) => e.!sid && e.!options);

 console.log(filteredResult);

filteredResult should be like

[
  {
    name: 'john',
    team: [12, 23, 34]
    
  },
  {
    name: 'john',
    team: [152, 233, 354]
  },
  {
    name: 'john',
    team: [152, 273, 314]
  }
];

>Solution :

array.map() should do it. Just return the specific properties that you want

var arr1 = [{
    name: 'john',
    team: [12, 23, 34],
    sid: 1023,
    options: {
      boolean: true
    }
  },
  {
    name: 'john',
    team: [152, 233, 354],
    sid: 1024,
    options: {
      boolean: true
    }
  },
  {
    name: 'john',
    team: [152, 273, 314],
    sid: 1025,
    options: {
      boolean: true
    }
  },
];

const result = arr1.map(x => ({
  name: x.name,
  team: x.team
}))

console.log(result)
