You define the sort2 method on [].__proto__ here, but the task requires implementing Array.prototype.sort using that predefined sort2. Currently there is no assignment that overrides Array.prototype.sort, so tests expecting a custom sort will fail.

const compare =
compareFunction ||
function (a, b) {
const A = String(a);
const B = String(b);

if (A > B) {
return 1;
}

if (A < B) {
return -1;
}

return 0;
};

for (let i = 1; i < this.length; i++) {
const current = this[i];
let j = i - 1;

while (j >= 0 && compare(this[j], current) > 0) {
this[j + 1] = this[j];
j--;
}

this[j + 1] = current;
}

return this;

After the sort2 implementation you should assign Array.prototype.sort to use it, e.g. Array.prototype.sort = function(compare) { return this.sort2(compare); };. Also ensure applyCustomSort() is called (or tests will call it) so the methods are actually installed.

The page only loads arrayMethodSort.js but does not invoke the exported applyCustomSort() installer. As a result your custom sort2/sort will not be installed — call applyCustomSort() (or modify the module to call it on load) so the prototype changes take effect before any sorting is done.

This line loads arrayMethodSort.js directly in the browser. The implementation file uses CommonJS (module.exports) and exports an installer function instead of running on load, which can cause ReferenceError: module is not defined and will not install the custom sort. Consider bundling the file for the browser, exposing and calling applyCustomSort() from a global, or converting the implementation to an ES module and importing it so the installer runs.
