What does () represents in someWords.toLowerCase(); and why we cannot simply call a method to variable like someWords.to toLowerCase?

21,074 PointsThat's right. For example in Java if you want to know the "length" of a String you would use the method "length"
string.length();
But if you want to know the length of an Array, you have to use the property length, use you would do it like this:
Array.length;
I hope that helps a little bit.

Treehouse TeacherIt just represents that you're calling the method toLowerCase on that string. String is an object in JavaScript and has many methods associated with it. Some methods take arguments... this one does not. You can view the MDN documentation on toLowerCase here https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/toLowerCase

One way to remember is () is calling a method.

7,246 PointsThanks, Daniel and *Carlos it clear right now. Now I should understand where to call method and where to call property.
