//Tugas3
// buatlah 2 program bebas dengan menggunakan promise seperti soal nomor 1


// const number = (num1, num2) => {
//     return new Promise((resolve, reject)=>{
//         if(typeof num1 === "number" && typeof num2 === "number"){
//             setTimeout(()=>{
//                 let result = num1 * num2
//                 resolve(result)
//             }, 3000)
//         }else{
//             const error = "inputan harus number"
//             reject(error)
//         }
//     })
// }

// number('a', 'b').then((res)=> {
//     console.log(res)
// })
// .catch((err)=>{
//     console.log(err)
// })
