Create an Engaging Addition Game Using Vue 3 and JavaScript

Chapter 1: Introduction to Vue 3
Vue 3 is the latest iteration of the user-friendly Vue JavaScript framework, designed for developing front-end applications. This guide will walk you through the process of creating an engaging addition game program using Vue 3 and JavaScript.
Section 1.1: Setting Up the Project
To begin, we will set up our Vue project using the Vue CLI. To install the CLI, you can use either of the following commands:
npm install -g @vue/cli
or
yarn global add @vue/cli
Once installed, run the following command to create your project:
vue create addition-game
Select the default options when prompted to set up the project.
Subsection 1.1.1: Developing the Addition Game
To construct the addition game, we start by creating a form element. This form will listen for submissions, utilizing the submit event. By employing the prevent modifier, we can ensure that submissions occur on the client side rather than the server side.
In the form, we will include an input field for users to enter their answers. We will bind this input to a reactive property called sum using v-model, automatically converting the input to a number with the number modifier. The button, which is set to type "submit," will enable us to trigger form submissions by emitting the submit event.
Within the component object, we define a data method that returns an object containing the initial values of all reactive properties. The computed property formValid allows us to verify whether the sum is greater than zero.
In our submit method, we will validate the form using the formValid property. If the form is valid, we retrieve the values of num1, num2, and sum, and check if num1 + num2 equals sum. If they match, we increment the score by one. Since num1 and num2 are generated using the Math.random function, we can confidently assume they are numbers. Additionally, we previously confirmed that sum is a number using the formValid computed property.
To generate num1 and num2, we call the generateQuestion method when the "Start Game" button is clicked or after the user submits an answer. The Math.random() method provides a number between 0 and 1, which we multiply to create a broader range. Finally, we use Math.ceil() to round the number up to the nearest integer.
