Why does the code fire three times and add nine items?

  My code
  

  var lvl1 = {
  '-': [], 
  '+': [] 
  } ;
  var lvl2 = {
  '~': lvl1, 
  '=': lvl1, 
  }
  var lvl3 = {
  'obj1':lvl2,  
  'obj2':lvl2,  
  'obj3':lvl2,  
  }
  var test1 = 'cor1[car1,-car2]cor2{<cop1,cop2,-cop3>}-cor3(cat3)cor4';
  
  console.log(test1)
  
  var text_default = test1.match(/(?<=^|\)|]|})[^\(|[|{]+/g);
  var text_tag = test1.match(/(?<=\[).+?(?=\])/g);
  var text_title = test1.match(/(?<=\{).+?(?=\})/g);
  var text_author = test1.match(/(?<=\().+?(?=\))/g);
  
  
  function add_plus_minus(way,arr){
  	$.each(arr, function(index2, value2 ) {
  		$.each(value2.split(','), function(index22, value22 ) {
  			var first = value22.slice(0,1)
  			var word = value22.replace(/[^A-Za-z0-9_]/g, "");
  			if(first=='-'){
  				lvl3[way[0]][way[1]]['-'].push(word);
  				alert('v')
  				console.log([way[0],way[1],'-']);
  				console.log(word);
  			}
  			else{
  				//lvl3[way[0]][way[1]]['+'].push(word);
  				//console.log([way[0],way[1],'+']);
  				//console.log(word);
  			}
  		});
  	});
  }
  
  
  function add_or_and(way,arr){
  	$.each(arr, function(index, value ) {
  		var and_arr = value.match(/(?<=^|\>)[^\<]+/g);
  		if(and_arr!=null){
  			add_plus_minus([way,'='],and_arr);
  		}
  		var or_arr = value.match(/(?<=\<).+?(?=\>)/g);
  		if(or_arr!=null){
  			add_plus_minus([way,'~'],or_arr);
  		}
  	});
  }
  
  var default_name = 'obj1';
  if(text_default!=null){
  console.log(text_default);
  add_or_and(default_name,text_default);
  }
  if(text_title!=null){
  console.log(text_title);  
  add_or_and('obj1',text_title);
  }
  if(text_author!=null){
  console.log(text_author);  
  add_or_and('obj2', text_author);
  }
  if(text_tag!=null){
  console.log(text_tag); 
  add_or_and('obj3',text_tag);
  }
  console.log(lvl3);

  
  The code had to add three elements.
  cor3 to lvl3 ["obj1"] ["="] ["-"]
  cop3 in lvl3 ["obj1"] ["~"] ["-"]
  car2 to lvl3 ["obj3"] ["="] ["-"]
  But I don't understand what went wrong?
  The code has added all three elements to each obj.

  Not surprisingly, you have all three properties of the lvl3 object referring to the same lvl2 object. In other words, with this notation lvl3 [way [0]] [way [1]] you always work with one object, and you need to separate.
