php - Extracting all the variables from a .js file or a JavaScript function -


is there way extract input, output , internal variables .js file name , type? if no, there way extract input, output , internal variables javascript function name , type?

i prefer use php or javascript world, other method can integrated php page or javascript function appreciated.

edit: mistake variable type. fogot it's not relevant in javascript.

if want objects type function in javascript file can directly in javascript in same page

var console = {    log: function(s) {      document.getelementbyid("console").innerhtml += s + "<br/>"    }  }    function allfunctions() {      var myfunctions = [];      (var l in this) {        try {            if (this.hasownproperty(l) &&            this[l] instanceof function &&            !/myfunctions/i.test(l)) {            myfunctions.push(this[l]);          }        } catch (ex) {}      }      return myfunctions;    } //allfunctions    function myfunction1(args) {    return "foo";  }    function myfunction2(args) {    return "bar";  }    var allfns = allfunctions();  (var f in allfns) {    console.log(allfns[f])  }
<div id="console" />

of course, depending on runtime execution scope, different results, executing in node.js scope limited node process.
