Learn JavaScript by developing simple projects.

How to learn JavaScript by developing simple projects? How to code mini projects in JavaScript? What can a beginner do with JavaScript to improve their skills? Do you want to build a portfolio but don’t have an idea for a project?

To progress in Javascript, you must practice by building projects. This is the best way to improve your code, especially if you are a beginner. In addition, these projects will constitute your portfolio which will allow you to create more opportunities for yourself as a JavaScript developer.

In this article, I give you examples of practical exercises for all levels. The former is aimed at beginners and is therefore easy to perform. We quickly level up on the latest examples of mini-projects.

By programming one of several of these exercises in JavaScript, you will be able to:

• To show concrete projects in your portfolio.
• To manipulate data in input (keyboard, mouse) as in output (screen).
• To build simple user interfaces on the web in HTML.

Let’s take a look at some sample projects and exercises for beginners in JavaScript.

1. Develop a TODO list in JavaScript

A TODO list is a great first mini-project to start learning about data entry and its display. By making a todo list, you will learn, for example:

• How to manage and display different elements according to their state
• How to create, retrieve, modify and delete objects in JavaScript
• How to go further with data permanence locally by exploring localStorage

A TODO list is a project that is often taken as an example when you learn frameworks or booksellers such as react, react-native, vue.js, angular.jsand others. Doing this project in JS Vanilla and HTML, therefore, makes a lot of sense and will facilitate your learning in the future.

2. Develop a JavaScript Quote Generator

Do you think creating a mini project that randomly gives quotes from your favorite rapper, author, or personality?

So take the opportunity to familiarize yourself with arrays and the Math.random () function in JavaScript by creating a quote generator.

1. First, you will need to collect the quotes you want, try to do this intelligently by scraping the data.
2. Then you will need to put these quotes in a table so that you can use them.
3. Eventually, you’ll build a UI to display the content randomly.

3. Develop a BMI Calculator in JavaScript

Doing a little calculator can also be a good exercise for JavaScript beginners. The formula for calculating BMI is simple:

const IMC = Weight * height** 2

With the Weightin kg, and the Heightin m.

All you have to do is build the data entry form and an HTML user interface to display the result.

To go further, you can also display the Body Mass Index category your user is in.

4. Develop a Currency Converter to JavaScript

Similar to the BMI calculator, the currency converter is a good, very simple exercise for basing your GitHub portfolio and getting your hands on JavaScript.

You will need the current course, which you can hard drive into your code or grab with an API. Then, with the amount entered as input by the user, you will display the result of your calculation to obtain the conversion of the chosen currency.

5. Develop a Calculator in JavaScript

Coding a good old-fashioned calculator is a great practical exercise for improving your JavaScript skills. You can have fun developing the GUI in HTML and CSS, then add intelligence with JavaScript.

Start with a few simple operators and basic buttons to manage:

• The bill
• The subtraction
• The multiplication
• The division

Then you can take into account the degrees, square roots, and all the other operations you want. A complete and successful calculator is a great JavaScript project to progress.

6. Developing a Countdown in JavaScript

Handling dates is a skill that will come in handy on a daily basis as a JavaScript or web developer. Even if some booksellers like moment.js help, you will need to use dates in your various projects. This is why making a small stopwatch, countdown timer or clock in JavaScript will familiarize you with the JavaScript Date API in addition to timeouts and intervals.

7. Developing a Word Counter in JavaScript

A word counter lets you know how many words there are in a text provided by the user. This feature comes in handy when you want to write an article with a minimum number of words, and sites even exist for the sole purpose of telling you how many words your text contains. This project will teach you how to manipulate strings and how to use a counter.

Basically, you want:

• a form so that the user can enter their text
• a button to validate the text
• the result of the number of words present in the text

To go further, you can also give the number of letters, the number of lines, the number of the same occurrence, and many other things.

8. Develop a Rock Paper Scissors Game in JavaScript

Did you know that scissors are the best choice in the rock paper scissors game? No? This is normal, is it not?

To verify this, you can code your own game. The computer will play a random hand from the 3 combinations and your objective will be to beat it. Three HTML buttons and the use of Math.random()will do the trick.

To go further, you can add a point counter, add intelligence to your artificial intelligence (rather than simple randomness) and make two computers play with each other.

9. Develop a YouTube clone in JavaScript

It is very easy to embed a video on your HTML pages. But it is also possible to use the YouTube API to perform searches and present the results in HTML. This project can be a bit more complicated than the others, but it will be perfect for getting you to understand how APIs work and how to make requests.

10. Develop a Google Maps clone in JavaScript

In the same vein as the YouTube clone, Google provides a simple API for manipulating Google Maps. You can have fun displaying what you want on a map based on a JavaScript object array for example.

11. Develop a Bot in JavaScript

Another way to learn Javascript with small, simple projects is to familiarize yourself with booksellers for making bots. You can easily make a bot that performs very simple tasks and ten lines of code.

Go further to progress even more with other JavaScript projects

I hope I have inspired you to create one or more of these projects in JavaScript.

The difference between having no projects in your portfolio at all and having a few small projects is huge. Practicing and posting projects in your spare time is proof that you have the right mindset to learn programming and that’s exactly what hiring companies want to see.
