Access argument name string inside the function
javascript
Solution
You could try something like this:
function myFunction (a, blabla, c, somethingElse, e, f) {
var obj = [];
//'(a, b, c, d, e, f)'
var tmp = arguments.callee.toString().match(/\(.*?\)/)[0];
//["a", "b", "c", "d", "e", "f"]
var argumentNames = tmp.replace(/[()\s]/g,'').split(',');
[].splice.call(arguments,0).forEach(function(arg,i) {
obj.push({
// question is how to get variable name here?
name: argumentNames[i],
value: arg
})
});
return obj;
}
console.log(JSON.stringify(myFunction(1, 2, 3, 4, 5, 6)));
//Output-> [{"name":"a","value":1},{"name":"blabla","value":2},
// {"name":"c","value":3},{"name":"somethingElse","value":4},
// {"name":"e","value":5},{"name":"f","value":6}]

Problem
Is it possible to access arguments name strings?! ``` function myFunction (a, b, c, d, e, f) { var obj = []; [].forEach.call(arguments, function(arg) { obj.push({ // question is how to get variable name here? name: "a",// "a", "b", "c", "d", "e", "f" value: arg, //a, b, c, ,d, e, f }) }); return obj; } myFunction(1,2,3,4,5,6); // return [{name: "a", value: 1}, {name: "b", value: 2}...] ``` Note: I know using `arguments` is not a good practice. I want to know if this even possible or not?
