ES5 :

var wor = 'alesh.3';
var key = 'last30m';

var record = json.data.rows.find(function(el) {
  return el.wor === wor;
});

var value = record ? record[key] : null;

ES6 :

const wor = 'alesh.3';
const key = 'last30m';

const { data: { rows } } = json;

const record = rows.find(el => el.wor === wor);
const value = record ? record[key] : null;
