Javascript undefined class function when missing semicolon -

function foo() {     var = this;     that.bar = function() {}     that.baz = function() {}      (function() {         that.baz();     }()); } new foo; 

uncaught typeerror: object #<foo> has no method 'baz'

that.bar works fine, it's last function doesn't exist. adding ; after baz function definition fixes everything.

i know excluding ; can mess things up, thought sure you're not supposed put ; after functions. no language that. why excluding ; after baz function cause break? should putting ; after function definitions?

you don't need semicolon after function declaration:

function foo() { } 

there no harm done if add semicolon, don't need it:

function foo() { }; 

that inserts empty statement after function declaration, has no effect. in same way, no harm, other confusing people read code:

var = 1;;;;;;;;;;;;;;;;;;;;;;;;;; 

otoh, do need semicolon after assignment statement:

that.prop = 1; 

and doesn't change if value you're assigning function expression:

that.foo = function() {};
