javascript - Function bringing back error 'token {'? -

-

i'm new javascript , i'm having hard time functions. tried this:

(function data {     // part that's broken seems?                 var data = 1;                 var real = 2;                 console.log(data + real) // })

i error: uncaught syntaxerror: unexpected token {

i'm not sure means though?

seems me, bit confused brackets... try this:

function data(){     var data = 1;     var real = 2;     console.log(data+real); }

the error suggests there problem token didn't expect there...

hope helps!
