arguments are both the subscript (or subscripts) and the value on the right-hand
side.

## Returning values

The body of a method is a [block](syntax.html#blocks). If it is a single
expression—more precisely if there is no newline after the `{` —
then the method implicitly returns the value of the expression.

Otherwise, the body returns `null` by default. You can explicitly return a
value using a `return` statement. In other words, these two methods do the
same thing:

<pre class="snippet">
method1() { "return value" }

method2() {
return "return value"
}
</pre>


However, it would be an error to include a `return` statment in method1():
<pre class="snippet">
method1() { return "return value" } //> Error at 'return': Expected expression.
</pre>
