Combine Array of Objects Only If Condition is Met [duplicate]

I've got an array of objects:

let events = [
  {"name": "blah", "end": "8"},
  {"name": "foo", "end": "9"},
  {"name": "bar", "end": "9"}
]

that I'd like to turn into a combined array, like so:

let events = [
  {"name": "blah", "end": "8"},
  {"name": "foo and bar", "end": "9"}
]

I know I can do this with a for loop and a new temporary holding array, but is there any JS Array function magic that could do this in one line? Something with reduce and/or map or something? My currently working loop code:

let combined = [];
for (let hour of events) {
  let alreadyExists = combined.find(x => x.end === hour.end);
  if (alreadyExists) {
    alreadyExists.name = alreadyExists.name + ' and ' + hour.name;
  } else {
    combined.push(hour);
  }
}
events = combined;
