Otherwise, we call the function that was passed down as a prop, which actually adds the todo item to our App’s state. If it is empty, we do nothing, and return from this function. Then we check to see if there is any text in the input field. This simply prevents the page from automatically refreshing when the form is submitted. Inside the handleSubmit function, first we have e.preventDefault(). This will call the component’s ‘handleSubmit’ function any time the user presses the submit button or presses the enter key. First, we’ve added an onSubmit listener to the form element. Since this article is not about CSS, I have included all the CSS you will need here: form You will see how this is done when we code the SubmitForm component. Anytime you have a form element, it is wise to make it a controlled component, meaning the data is managed by React, not the DOM. The only other class based component I think we will need is the SubmitForm component. So, our app component needs to be a class based component so we can store all of the tasks in the state.

SubmitForm - This is the form that is used to add new todos to the list.We will probably make a single ‘todo’ component for each individual row, but we will handle that when we get there.

TodoList - This is a container for the list of todos.

I am going to make mine show how many total tasks are in the list.

Header - This will simply display some message above all of the tasks.

So it looks like we will need to build three primary components…
