Simple question, how do I document that "Mixed-type"? I know I could just list all possible types like {null|undefined|String|Number|Object}
and end up finding myself missing one and making it overly complex. I tried using the Mixed keyword, but it popups errors in many IDEs such as WebStorm.
I found the way to do it:
/**
* @param {*} foo
*/
function bar(foo) {}
