Hey folks, I just wanted to highlight a new AS3 language feature that I have recently implemented in the Royale compiler: arrow function expressions!
If you're not familiar, these were added to JavaScript a while back. Here are the MDN docs for the JS version: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions Basically, they have two main advantages. 1. They have shorter syntax. 2. They can use the `this` variable from the enclosing function's scope. Here's a simple example: var func:Function = (name:String) => "Hello, " + name; func("Royale"); - No function keyword (uses => instead) - Optional return type (it may be inferred from the return value) - Optional braces around the function body, if it contains a single expression - If braces are omitted, no need for a `return` keyword You could rewrite the same arrow function like this, without everything omitted: var func:Function = (name:String):String => { return "Hello, " + name; } Technically, this is valid too: var func:Function = name => "Hello, " + name; However, it will report a warning because the name parameter type is missing, so that's not recommended. -- Josh Tynjala Bowler Hat LLC https://bowlerhat.dev/
