In coding RAMP-TS scripts in JavaScript these code fragments are all standard and equivalent:

x = new Object();
x.a = 1;
x.b = "Hello"; 
  
-----------------------------------------
  
x = { a : 1, b : "Hello" ) 
  
-----------------------------------------
  
x = { "a" : 1, "b" : "hello" }  <========= which is the JavaScript format that was chosen for use in AJAX-JSON strings.   
  
-----------------------------------------
  
x = { };
x["a"] = 1;
x["b"] = "hello"; 
  
-----------------------------------------
  
x = new Object();
x["a"] = 1;
x["b"] = "hello"; 
  
-----------------------------------------
