var str1 = new String(1) var str2 = String(1) console.log("Valor é %s e o tipo é %s", str1, typeof(str1)); console.log("Valor é %s e o tipo é %s", str2, typeof(str2));

var a = new String(1); var b = String(2); console.log(a.concat); console.log(b.concat); console.log(a.substr); console.log(b.substr);
Note : We do not need to focus only on
String , since this is true for calls of
