Remove a particular name inside an array

Question

{
  "list": [{
      "name": "car",
      "status": "Good",
      "time": "2018-11-02T03:26:34.350Z"
    },
    {
      "name": "Truck",
      "status": "Ok",
      "time": "2018-11-02T03:27:23.038Z"
    },
    {
      "name": "Bike",
      "status": "NEW",
      "time": "2018-11-02T13:08:49.175Z"
    }
  ]
}

How do I remove just the car info from the array.

To achieve expected result, use filter option to filter out car related values

var obj = {"list":[ {"name":"car", "status":"Good", "time":"2018-11-02T03:26:34.350Z"}, {"name":"Truck", "status":"Ok", "time":"2018-11-02T03:27:23.038Z"}, {"name":"Bike", "status":"NEW", "time":"2018-11-02T13:08:49.175Z"} ]}

let result = {
  list: []
}
    
result.list.push(obj.list.filter(v => v.name !=='car'))
console.log(result)

Option 2: without using filter as requested by OP

Use simple for loop to achieve same result

var obj = {"list":[ {"name":"car", "status":"Good", "time":"2018-11-02T03:26:34.350Z"}, {"name":"Truck", "status":"Ok", "time":"2018-11-02T03:27:23.038Z"}, {"name":"Bike", "status":"NEW", "time":"2018-11-02T13:08:49.175Z"} ]}

let result = {
  list: []
}
    
 for(let i =0; i< obj.list.length; i++){
   if(obj.list[i].name !== 'car' ){
     result.list.push(obj.list[i])   
   }

 } 
console.log(result)

Is there any way that the result can be achieved without using filter – sam Nov 15 '18 at 19:12
@Nick, use simple for loop , updated my answer – Naga Sai A Nov 15 '18 at 19:41
I tried to use that but i have this TypeError: Cannot call method "push" of undefined. – sam Nov 15 '18 at 21:27
check variables names which could be causing issue , as my code works from snippet – Naga Sai A Nov 15 '18 at 21:29
Now i'm getting a new error TypeError: Cannot read property "0.0" from undefined any idea? – sam Nov 16 '18 at 15:45
var value = JSON.stringify(json); var count = json.data.serverlist.length; System.debug(count) var value = JSON.stringify(json.data) var result = { list:[] } for(var i =0; i< count; i++){ if(value.list[i].name !== "car" ){ result.list.push(value.list[i]) } } System.debug(result); – sam Nov 16 '18 at 15:46
above code giving me an error – sam Nov 16 '18 at 15:47
remove JSON.stringify for value and use var value = json.data and try – Naga Sai A Nov 16 '18 at 15:48
Sai Thanks!!! It works – sam Nov 16 '18 at 15:56
glad it worked ... mark my post as answer , if it worked for you – Naga Sai A Nov 16 '18 at 15:58

const obj = JSON.parse(jsonString);
let yourArray = obj.list;


  let filteredArray = yourArray.filter(elem => elem.name !== "car");

You forgot to parse it. – squeekyDave Nov 15 '18 at 16:35
Parse what @squeekyDave ? Op says they have an array not json – charlietfl Nov 15 '18 at 16:42
@charlietfl the data passed is obviously a JSON. – squeekyDave Nov 15 '18 at 16:45
@squeekyDave that is not a given. Could be hard coded into variable, or already parsed such as using `fetch()` or `$.getJSON`. OP specifically asked about *"array"* – charlietfl Nov 15 '18 at 16:46
@charlietfl What do you mean is not given? It is the only thing the OP has posted. – squeekyDave Nov 15 '18 at 16:47

@filip can we do it without using filter option? – sam Nov 15 '18 at 19:13
@Nick you mean to keep the old array with the filtered options without creating a new one? Why would you want that? – filip Nov 15 '18 at 21:59
@filip was trying to remove one of the object in that...seems like having some issues when using filter and I tried using push it’s not working...please give me any other way of solving this issue – sam Nov 16 '18 at 02:53
@Nick still don't know what you are trying to achieve – filip Nov 16 '18 at 18:09
