Assignment operators do not follow the conventional rule of the first character preference. Rather a method which is followed by an equal sign will have the same precedence as the assignment operator =. The exception to this rule is comparison operators such as <= and != which will follow the first character rule as discussed above.

A Good Practice

While operator precedence is a valid and supported part of Scala, it is still better to show precedence using parenthesis (). This avoids any and all confusion that a programmer reading your code might have.

And on this note, our discussion on operators comes to an end. In the next lesson, you will be challenged to use your knowledge on operator precedence.
