() is Null?

() is null in javascript, right?

[L.E.D]

() is null in javascript, right?

 

I thought you had to define it null? 

 

like 

 

String stuff = null;

In this string for example:

Color = Data(function() ({ Red: {}, Green: {}, Blue: {}, Yellow: {} })) Point = Data(function() ({ Pt: { x: Number, y: Number, color: Color } }))

Yea it is kinda a null, but mainly for non-attributes.

Thanks for answering that question exactly how I was going to

I'm more used to regular Java, but after looking around, I believe you are correct for javascript. 

 

Javascript and Java are entirely unrelated

In this string for example:

Color = Data(function() ({ Red: {}, Green: {}, Blue: {}, Yellow: {} })) Point = Data(function() ({ Pt: { x: Number, y: Number, color: Color } }))

That just means you are defining an anonymous function with no parameters.

yes

i know

i had numbers inside of the ()

but without them it was stated as null right

[squirrl]

I think i see what you are trying to say.

 

For example you could have

function takeAFunction(callback, number) { // usually you would have params before the callback though  if (!number) {    return callback && callback('number is null');  }  callback && callback(null, number);}

and then call it like this:

takeAFunction(function(err, res) { console.log(err, res); // will print out "null 1"}, 1);

or like this

takeAFunction(function(err, res) { console.log(err, res); // since number wasn't passed in it will be null and handled as such in "takeAFunction". This will print "number is null null"});

or like this

takeAFunction(1, function() { console.log(err, res); // err and res would be passed in to the anonymous function when called by takeAFunction, but since this particular function does not define them, they will be undefined when logged.});

Basically () is not resolved to null or any other type. It's just formatting. Any parameters which would have been passed into that anonymous function will not be initialised and be undefined. (not null)
