// Your hookbin URL goes here:
const url = "";
      const formEl = document.querySelector("form");
      formEl.addEventListener("submit", async (e) => {
        e.preventDefault();
        const formData = new FormData(formEl);
        const formDataSerialized = Object.fromEntries(formData);
        const jsonObject = {
          ...formDataSerialized,
          sendToSelf: formDataSerialized.sendToSelf ? true : false,
        };
        try {
          const response = await fetch(url, {
            method: "POST",
            body: JSON.stringify(jsonObject),
            headers: {
              "Content-Type": "application/json",
            },
          });
          const json = await response.json();
          console.log(json);
        } catch (e) {
          console.error(e);
          alert("there as an error");
        }
