Part 3:- Try Catch javascript Syntax

Javascript Code

const btn = document.getElementById("btn");
const divdata = document.getElementById("divdata");

//Work with remote api
// Promise then | Single Data
// const makeRequest = async() => {
//     console.log(1)
//     fetch("http://127.0.0.1:8000/student/")
//     .then((res) => {
//         if (!res.ok){
//             console.log(res.statusText);
//         }
//         return res.json();
//     }).then((data) => {
//         console.log(data);
//     }).catch((err) => {
//         console.log(err)
//     })
// }

// Async & Await 
// const makeRequest = async () => {
//     try {
//         const res = await fetch("http://127.0.0.1:8000/student/");
//         if (!res.ok) {
//             throw new Error(res.statusText)
//         }
//         const data = await res.json();
//         console.log(data);
//         data.forEach((item) => {
//             divdata.innerHTML += `${item.title} - ${item.desc} <hr>`
//         })
//     } catch (error) {
//         console.log('error', error);
//     }
// }


// Promise Then | POST REQUEST
// const makeRequest = () => {
//     const init = {
//         method: "POST",
//         headers: {
//             'Content-Type': 'application/json'
//         },
//         body: '{"title": 10, "desc": 10}'
//     }
//     fetch("http://127.0.0.1:8000/student/", init)
//         .then((res) => {
//             if (!res.ok) {
//                 console.log(res.statusText);
//             }
//             console.log("res", res);
//             return res.json();
//         }).then((data) => {
//             console.log(data);
//         }).catch((err) => {
//             console.log("error", err);
//         });
// }

const makeRequest = async () => {
    try {
        const init = {
            "method": "PUT",
            "headers": {
                "Content-Type": "application/json"
            },
            "body": '{"title": 100, "desc": 100}'
        }
        const res = await fetch("http://127.0.0.1:8000/student/630e306ba6306216f4fde80a", init);
        if (!res.ok) {
            throw new Error(res.statusText);
        }
        const data = await res.json();
        console.log(data);
    } catch (error) {
        console.log("error", error);
    }
}

btn.addEventListener('click', makeRequest);
