Practical functional programming library for TypeScript

    return inferred.apply(undefined, arguments);
}
const inferred = infer((array, whileFn, reduceFn, initialValue) => {
    let accumulator = initialValue;
    for (let index = 0; index < array.length; index++) {
        const item = array[index];
        const next = reduceFn(accumulator, item, index, array);
