+For **Scala 2**, there is a [complete answer on Stack Overflow](https://stackoverflow.com/a/2530007/4111404)
 and a [summary with practical differences](https://tpolecat.github.io/2014/06/09/methods-functions.html).
 
-Note that in **Scala 3** the differences are fewer;
-for example, they will be able to

-as well as [type parameters]({{ site.scala3ref }}/new-types/polymorphic-function-types.html).

-Nevertheless, it is still recommended to use methods most of the time,
-unless you absolutely need a function. And, thanks to

-you rarely would need to define a function rather than a method.
+In **Scala 3**, the differences are fewer.
+[Context functions]({{ site.scala3ref }}/contextual/context-functions.html)

+It's standard to use methods most of the time,

+[Eta-expansion](https://stackoverflow.com/questions/39445018/what-is-the-eta-expansion-in-scala),
+converts methods to functions when needed.
+For example, a method such as `map` expects a function,
+but even if you `def square` as shown above, you can
+still `xs.map(square)`.
