// 示例1

}
curry(mysetTimeout, () => console.log("hello1"), 1000)

let delayTenMsCurry = curry(mysetTimeout);

let delayTenMs = delayTenMsCurry(() => console.log("hello3"));

// 示例2
function addFn(a, b, c, d, e, f, g) {
    return a + b + c + d + e + f + g
}
let add = curry(addFn);

// 全部参数一次性传递
console.log(add(1, 2, 3, 4, 5, 6, 7))

// 参数分批传递
console.log(add(1)(2, 3, 4)(5, 6, 7))

// 每个参数单独传递
console.log(add(1)(2)(3)(4)(5)(6)(7))
