typescript - What does the "=> any" signify? -

-

in answer this question s/he refers to:

getjson(url: string, success?: (data: any, textstatus: string, jqxhr: jqueryxhr) => any): jqueryxhr;

i understand "success?: (data: any, textstatus: string, jqxhr: jqueryxhr)" part - that's saying there optional function called on success has 3 typed parameters.

but "=> any" signify in this? mean function can return type of object? doesn't make sense success function logically of type void.

thanks - dave

you correct; void correct way type function's return value.

in practice, there isn't difference between any , void return types in callback positions because compiler not enforce functions type of any have return statement.
