✅

You can use the includes method to find if the element is present in the array or not.

The includes() method determines whether an array includes a certain
value among its entries, returning true or false as appropriate. – MDN

if(!location_ids.includes(user.location_id)){}

const user = {
  first_name: "James",
  last_name: "Smith",
  location_id: 21,
};
const location_ids = [23, 31, 16, 11];

if (!location_ids.includes(user.location_id)) {
  console.log("Select user");
}

// Change location ID
user.location_id = 11;

if (!location_ids.includes(user.location_id)) {
  console.log("Select user");
} else {
  console.log("Don't select user");
}
