Rules inconsistency: function declaration and function invocation, with or without space between function name and `(`

[xieranmaya]

Function declaration:

function fun (arg) { //space between fn name and (
}

Function invocation:

fun(123) //no space between fn name and (

I think it's and inconstancy and the above one do not need SO MUCH spaces and JSbeautifier removes the space between fn name and the (, thus large amount old code do not follow the Standard.

Most popular frameworks/libraries also do not reverse the space between function name and the (, like Angular, Lodash and React:
Angular: https://github.com/angular/angular.js/blob/master/src/ng/controller.js#L26
Lodash: https://github.com/lodash/lodash/blob/master/lodash.js#L381
React: https://github.com/facebook/react/blob/master/src/isomorphic/classic/element/ReactElement.js#L114

Chrome DevTools also format it without spaces:
