You can enhance code readability and maintainability by refactoring the submit event listener into two separate functions. The first function can be used to add the input values to taskData, while the second function can be responsible for adding the tasks to the DOM.
Use arrow syntax to create an addOrUpdateTask function. Then move the dataArrIndex variable, the taskObj object, and the if statement into the addOrUpdateTask function.
Your code so far
// Define addOrUpdateTask function using arrow syntax
const addOrUpdateTask = () => {
// For the findIndex() method, pass in an arrow function with item as the parameter.
const dataArrIndex = taskData.findIndex((item) => item.id === currentTask.id);
// Create a taskObj object with an id property
const taskObj = {
// add another hyphen("-") and then Date.now() to make the id unique
id: `${titleInput.value.toLowerCase().split(' ').join('-')}-${Date.now()}`,
date: dateInput.value,
title: titleInput.value,
description: descriptionInput.value
};
if (dataArrIndex === -1) {
taskData.unshift(taskObj); // unshift puts taskObj at the front of the taskData array
}
};
