pass parameter to callback function which referenced by name when passed

I have two functions:

array_sort(array, compare_function)
compare_values(value1, value2, case_insensitive)

The function 'array_sort' uses 'compare_values' function to compare values and passes only two values to it, while the 3rd parameter 'case_insensitive' should be passed when using the function 'array_sort'. The only way I know how to do that is to wrap 'compare_values' function into another function:

var my_array = [];
var case_insensitive = true;
var wrapper = function(value1, value2) {
    compare_values(value1, value2, case_insensitive)
}
array_sort(my_array, wrapper);

Is there any other way I can do that?

You can write another function to abstract over the wrapper:

function makeWrapper(case_insensitive) {
    return function wrapper(value1, value2) {
        compare_values(value1, value2, case_insensitive)
    };
}

array_sort(my_array, makeWrapper(true));
