Why are arrays not equal in js?

Question

JavaScript

Let's say we have a function, on the input of which we expect to see the text

function parseRoomName(text) {
  var auditoryName = text.split('');
}

we take and turn the text into an array and return it

function parseRoomName(text) {
  var auditoryName = text.split('');
  return auditoryName
}

What happens if we enter parseRoomName('K-200')?
["K", "-", "2", "0", "0"]
Everything is as it should be, right?
And now let's try to make this function remove hyphens that could get into the text input.

function parseRoomName(text) {
  var auditoryName = text.split('');
  for (var i = auditoryName.length - 1; i >= 0; i--) {
    if (auditoryName[i] == '-') {
      auditoryName.splice(i,1);
    }
  }
  return auditoryName
}

Now we enter parseRoomName('K-200'), and we get We ["K", "2", "0", "0"]
enter , and we parseRoomName('K200')also get ["K", "2", "0", "0"]
But they are not equal!
If we enter parseRoomName('K-200') == parseRoomName('K200'), we get false
If we enter

parseRoomName('K-200').length == parseRoomName('K200').length

, then we get true
If we enter

parseRoomName('K-200')[1]== parseRoomName('K200')[1]

, then we also get true
What's wrong with this life?

Answer 1

Arrays are compared by reference, not by value.
[] != []

Answer 2

If you want to compare arrays, then write a function that first compares the length of the array, and then bypasses the arrays and compares the elements manually.

Answer 4

["K", "2", "0", "0"].join( ',' ) == ["K", "2", "0", "0"].join( ',' );
JSON.stringify( ["K", "2", "0", "0"] ) == JSON.stringify( ["K", "2", "0", "0"] );
