How to Learn Javascript: Getting Started

If you’re interested in learning JavaScript, there are a few things you need to do to get started. In this section, we’ll cover the basics of setting up your environment and getting started with JavaScript fundamentals.

Setting Up Your Environment

Before you can start writing JavaScript code, you need to set up your development environment. Here are the basic steps you need to follow:

  1. Choose a code editor. There are many code editors available, both free and paid. Some popular options include Visual Studio Code, Atom, and Sublime Text. Choose one that you’re comfortable with and that has good support for JavaScript.
  2. Install a web browser. You’ll need a web browser to test your JavaScript code. Chrome, Firefox, and Safari are all good options.
  3. Set up a local development server. If you’re working with JavaScript on the web, you’ll need a local development server to test your code. You can use a tool like Node.js or Apache to set up a local server.

JavaScript Fundamentals

Once you have your environment set up, you can start learning JavaScript fundamentals. Here are some key concepts you should focus on:

  1. Variables. In JavaScript, you use variables to store and manipulate data. You can declare variables using the var, let, or const keywords.
  2. Objects. Objects are a fundamental data type in JavaScript. They allow you to store related data and functions together.
  3. Methods and Properties. Objects in JavaScript have methods and properties. Methods are functions that can be called on an object, while properties are values that are stored in an object.
  4. Events. In JavaScript, you can use events to trigger code when something happens on a web page. For example, you can use the click event to run code when a user clicks on a button.

Remember, learning JavaScript takes time and practice. Don’t be discouraged if you don’t understand everything right away. Keep practicing and experimenting, and you’ll soon be writing JavaScript code like a pro!

Practice Makes Perfect

If you want to learn JavaScript, practice is key. The more you practice, the more you’ll learn and the better you’ll become. Here are some ways you can practice:

Tutorials and Examples

Tutorials and examples are a great way to learn JavaScript. They provide step-by-step instructions and show you how to use JavaScript in real-world situations. You can find tutorials and examples online, in books, and in courses. Some popular websites for JavaScript tutorials include W3Schools, Mozilla Developer Network, and freeCodeCamp.

When you’re going through a tutorial or example, make sure you understand each step before moving on to the next one. Take notes and try to apply what you’ve learned to your own projects.

Coding Challenges

Coding challenges are another way to practice JavaScript. They provide you with a problem to solve using JavaScript. Some popular websites for coding challenges include HackerRank, CodeWars, and Project Euler.

When you’re working on a coding challenge, take your time and read the problem carefully. Break it down into smaller parts and try to solve each part individually. Don’t be afraid to ask for help if you get stuck.


Taking quizzes is a great way to test your knowledge of JavaScript. You can find quizzes online, in books, and in courses. Some popular websites for JavaScript quizzes include Codecademy and Quizlet.

When you’re taking a quiz, read each question carefully and make sure you understand what it’s asking. Don’t rush through the quiz and take your time. After you’ve taken the quiz, review your answers and try to understand why you got each question right or wrong.

Remember, practice makes perfect. The more you practice JavaScript, the better you’ll become. Try to practice every day and don’t be afraid to make mistakes. With time and practice, you’ll become a JavaScript pro.
