Property renaming

[doctor8296]

That's it we need that xD

Not planned. Too error-prone. It would most likely struggle with dynamic keys, just like Obfuscator.io's renameProperties (even on 'safe' mode):

// Input
(function () {
    const foo = {
        prop1: 1,
        prop2: 2,
        calc: function () {
            return this.prop1 + this.prop2;
        },
    };

    function doStuffWithFoo(foo) {
        var calc = "cal" + "c";
        console.log(foo[calc]());
    }

    doStuffWithFoo(foo);
})();
// 3

// Output
(function () {
    const _0x1ded56 = {
        '_0x7aa8af': 0x1,
        '_0x204e8e': 0x2,
        '_0x3d83a6': function () {
            return this['_0x7aa8af'] + this['_0x204e8e'];
        }
    };
    function _0x19b102(_0x420ffb) {
        var _0x643b75 = 'cal' + 'c';
        console['log'](_0x420ffb[_0x643b75]());
    }
    _0x19b102(_0x1ded56);
}());
// Uncaught TypeError: _0x18422a[_0x4ce7a3] is not a function

Object Extraction is safe alternative that can be used to rename property names by first converting them to individual variables.

Unless there is a concrete way to safely replace property names then I won't risk adding it. PRs are welcome to implement it.

if values are static this could be posible if you pre evaluate all string conversions but it woudl be horrible to implement plus if it acces a property from for example a http request or something that is not in the code itself would be imposible.
