How to understand this JS code?

(function(_0x900076, _0x10f0f6) {
    var _0x25d734 = function(_0x217172) {
        while (--_0x217172) {
            _0x900076["push"](_0x900076["shift"]());
        }
    };
    _0x25d734(PP_0x10f0f6);
}(_0x4913, 0x64));

this is generally tool generation and appears to be designed to test the performance of array methods. The
can be understood by changing it into semantic point variables.

console.time('test')
var arr = [1,2,3,4,5,6,7,8,9];
(function(a, index) {
    var fn = function(v) {
        while (--v) {
            a['push'](a['shift']());
        }
    };
    fn(PPindex);
}(arr, 0x64));
console.timeEnd('test')
