How to remove JSON Object from a JSON Array?

Question

var alldesignationsarr = ['Employee','Manager'];

[`Array.filter()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter) — Satpal, Jun 19 '18 at 10:59
There is no JSON in your question. JSON is a *textual notation* for data exchange. [(More here.)](http://stackoverflow.com/a/2904181/157247) If you're dealing with JavaScript source code, and not dealing with a *string*, you're not dealing with JSON. Your question is simply about removing an object (not a "JSON object') from an array (not a "JSON array"). — T.J. Crowder, Jun 19 '18 at 11:01

You can use desgdescarr.filter():

var alldesignationsarr = ['Employee','Manager'];

var desgdescarr = [{
    "designation": {
        "name": "Employee",
        "ptest": {}
    },
    
    "designation": {
        "name": "Manager",
        "ptest": {}
    },
    "designation": {
        "name": "Managers",
        "ptest": {}
    }
}];
    
var res = desgdescarr.filter((obj) => alldesignationsarr.indexOf(obj.designation.name) === -1);
console.log(res);

If you want to make changes to the original array then you can also use a simple forEach logic for that:

var alldesignationsarr = ['Employee','Manager'];

var desgdescarr = [{
    "designation": {
        "name": "Employee",
        "ptest": {}
    },
    
    "designation": {
        "name": "Manager",
        "ptest": {}
    },
    "designation": {
        "name": "Managers",
        "ptest": {}
    }
}];
    
desgdescarr.forEach((obj, index) => {
  if(alldesignationsarr.indexOf(obj.designation.name) !== -1){
    desgdescarr.splice(index,1);
  }
});

console.log(desgdescarr);
