How to make to do list on JavaScript

This article will show you how to create a to-do list using JavaScript, including an example to help you get started.

Making To Do List With JavaScript

Making a to do list with JavaScript is very easy. This tutorial will show you the basics of creating a to do list using JavaScript. You will learn how to create a list of tasks, add items to the list, and delete items from the list. You will also learn how to save your to do list in a file so that you can access it later.

The first step in making a to do list with JavaScript is to create an array that will store the list of tasks. An array is a set of data that can be accessed by an index. The array will store the tasks in the order that they are added to the list. The code below creates an empty array called "tasks" that will store the list of tasks.

let tasks = [];

The next step is to create a function that will add items to the list. This function will take two parameters: a task name and a priority level. The function will add the task to the "tasks" array and set its priority level. The code below shows an example of a function that adds an item to the to do list.

function addTask(taskName, priority) {
  let task = {
    name: taskName,
    priority: priority
  };
  tasks.push(task);
}

The next step is to create a function that will remove items from the list. This function will take one parameter: the task name. The function will search the "tasks" array for the task name and then remove it from the array. The code below shows an example of a function that removes an item from the to do list.

function removeTask(taskName) {
  for (let i = 0; i < tasks.length; i++) {
    if (tasks[i].name == taskName) {
      tasks.splice(i, 1);
      break;
    }
  }
}

The last step is to create a function that will save the list of tasks to a file. This function will take one parameter: the file name. The function will save the "tasks" array to the file and then close the file. The code below shows an example of a function that saves the to do list to a file.

function saveTasks(fileName) {
  let file = fs.createWriteStream(fileName);
  file.write(JSON.stringify(tasks));
  file.end();
}

Now that you have created the functions to add, remove, and save items to the list, you can create a simple user interface to allow users to interact with the list. This is beyond the scope of this tutorial, but it is a good idea to create a user interface if you plan to use your to do list in a project.

In conclusion, making a to do list with JavaScript is a simple and straightforward process. By creating an array to store the list of tasks, creating functions to add, remove, and save items to the list, and creating a user interface to allow users to interact with the list, you can easily create a to do list with JavaScript.
