This is your correct json

{
 "slug": "test",
 "logo": "dd3d769a86d4c8a91dcbf05bf22e04eda7b73e04.png",
  "publishers": [
 {
 "name": "publisher 1",
 "magazines": [
  {
    "name": "name-1",
    "startDate": "2020-09-01T00:00:00+0000",
    "endDate": "2021-09-02T00:00:00+0000",
    "enabled": false,
},
{
    "name": "name- 2",
    "startDate": "2020-09-11T00:00:00+0000",
    "endDate": "2020-09-18T00:00:00+0000",
    "enabled": true,
},

{
    "name": "name- 2",
    "startDate": null,
    "endDate": null,
    "enabled": false,
    
  }]
  },
 {
"name": "publisher 2",
"magazines": [
  {
    "name": "name- 1",
    "startDate": null,
    "endDate": null,
    "enabled": true,
},
{
    "name": "name - 2",
    "startDate": null,
    "endDate": null,
    "enabled": false,
}]
}],
"locale": "in",
}

and try this code:

 var testObj={your Json data...};
  for(i=0; i < testObj.publishers.length; i++){
        if(testObj.publishers[i].enabled == false){
            //console.log('exist');
            testObj.publishers.splice(i, 1);
        }

    }

with map and filter:

const testObj = {yourObject...}

testObj.publishers.map(publisher => (publisher.magazines.filter(magazine => magazine.enabled === true)[0]))

Same as any other array: With Array.filter

let origdata = {...}

for (let publisher of origdata.publishers) {
  publisher.magazines = publisher.magazines.filter(x => x.enabled === true);
}
