自动化封装柯里化函数

function foo(a, b, c) {
    console.log(a + b + c)
}
function hyCurrying(fn) {
    function curryFn(...args) {
        if (args.length >= fn.length) {
            fn(...args)
        } else {
            return function (...newArgs) {
                return curryFn(...args.concat(newArgs))
            }
        }
    }
    return curryFn
}
//    debugger
const newFoo = hyCurrying(foo)
