I want to create this function:

const hasObject = (myObjectSet: Set<MyObject>) => {
  if (myObjectSet.size === 0) {
    return false
  }
    
  // test if there is an object with id 4
}

The equivalent of some for an array.

EDIT

I made it like this at the end:

const hasObject = (myObjectSet: Set<MyObject>) => {
  if (myObjectSet.size === 0) {
    return false
  }
    
  let result = false

  myObjectSet.forEach((myObject) => {
    if(myObject.id === 4) {
      result = true
    }
  }) 

  return result
}
