Remove data containing string from object

I want to ask how do I remove strings from data. Lets say I have a data:

var data = {DeviceID: "101", ManufacturerID: "9", ManufacturerName: "Toshiba", Device Name: "Toshiba - Tecra R950", Price: "200"};

how do I remove ManufacturerName and Device Name because they do not have numbers?

The simplest method - if you're happy with mutating the object rather than creating a new one - is to iterate over the object properties, and try to coerce each value to a number. If it's not a number remove the property.

const data = { DeviceID: '101', ManufacturerID: '9', ManufacturerName: "Toshiba", 'Device Name': 'Toshiba - Tecra R950', Price: '200' };

for (let key in data) {
  if (!Number(data[key])) delete data[key];
}

console.log(data);

Object.entries().filter(([key,value]) => !Number.isNaN(Number.parseInt(value))

You can do it like this-

const data = {DeviceID: "101", ManufacturerID: "9", ManufacturerName: "Toshiba", DeviceName: "Toshiba - Tecra R950", Price: "200"};
const res = Object.fromEntries(
  Object.entries(data).filter(([key, value]) => !isNaN(Number(value)))
);
console.log(res);
