Answer 1

let obj = {
  field: 'name',
  value: 'peter',
  field1: 'email',
  value1: 'test@gmail.com',
  field2: 'id',
  value2: '2345'
};

let result = Object.keys(obj)
  .filter(key => key.indexOf("field") === 0)  // we're only interested in the "fieldX" keys
  .map(field => [obj[field], obj[field.replace("field", "value")]]); // build the array from the "fieldX"-keys

console.log(result);
