Javascript alias for "Function" keyword

Question

Ahoi community,

Is there a possibility to define an alias for the javascript keyword "Function"?

var f = Function; // define Function alias

var foobar = f() // write 'f' as replacement for 'function'
{        
    console.log("foobar") 
};

foobar();

You can't create aliases for keywords, though Function is not a keyword, it's the name of a function. — Teemu

Arrow functions is what I was looking for (thx Xufox).

It's useful to minify your JS (thx Beejor).

To me it is also better readable and faster to code :)

So the snippet in the original question would look like:

var foobar = () => console.log("foobar"); 

foobar();

Is it more readable for the other developer that you work with?

It reduce 8 chars. If ES6 devs had thought a little further they could have let reduce the parens (those around parameters) and in this case also the '='. Would reduce 11 chars and be much more elegant: var foobar => console.log("foobar")

No you cannot, but you can have anonymous functions, named functions and/or function expressions.

For example,

//named function
function Test( param1, param2) { /* code goes here */}

//function expression
var foo = function (param1, param2) { /* code goes here */}
foo('test1','test2')

//anonymous function
function (param1, param2) { /* this is one is problematic */}

I recommend you go through a javascript tutorial basics.
