Question

I\'ve been learning scala and I gotta say that it\'s a really cool language. I especially like its pattern matching capabilities and function literals but I come from a javascri

I think what you mean "lazy function" is function literal or anonymous function.

In Scala you could do things like this, very similar to the javascript code you posted.

val foo = () => {
    val t = new Date()
    val foo = () => {t}

    foo()
}

println ("Hello World:" + foo())

The main difference is that:

• You could not re-assignment the outer foo
• There is no "function" keyword, instead you use something like (s:String) => {code}
• The last statement is the return value of a block, so you don't need add "return".
