## Introduction

JavaScript is a versatile and popular programming language that is widely used to create dynamic and interactive websites. If you're new to programming and want to get started with JavaScript, this tutorial is for you!

In this guide, we'll cover the basics of JavaScript and provide you with the knowledge and tools you need to get started. By the end of this tutorial, you should have a solid foundation in JavaScript and be ready to take your skills to the next level.

### Learn the basics of programming

Before diving into JavaScript, it's important to have a basic understanding of programming concepts. Some key concepts to learn include:

- Variables: used to store and retrieve data
- Data types: such as numbers, strings, and Booleans
- Operators: used to perform operations on data, such as addition and comparison
- Control structures: such as loops and conditional statements

There are many resources available online that can help you learn these concepts. Codecademy and Khan Academy are two popular platforms that offer interactive tutorials and exercises to help you practice and solidify your knowledge.

### Set up your development environment

To start writing and running JavaScript code, you'll need to set up a development environment. Here are the tools you'll need:

A text editor: This is where you'll write your code. Some popular options include Sublime Text, Atom, and Visual Studio Code.
A web browser: You'll use a web browser to run your JavaScript code. All modern web browsers support JavaScript, so you can use whichever one you prefer.

### Get familiar with the syntax

JavaScript has its own set of rules and conventions for writing code, known as syntax. Some key things to know about JavaScript syntax include:

JavaScript is case sensitive
Statements must end with a semicolon
Code is written in blocks using curly braces
Comments are denoted using double slashes (//)

### Start coding!

Now that you have a development environment set up and know the basics of JavaScript syntax, it's time to start writing some code! Here are a few exercises to get you started:

- Print a message to the console: Use the `console.log()`  function to print a message to the console.
- Create a simple function: Define a function using the function keyword and call it using its name followed by parentheses.

Example:
```
function doSomething(){
    console.log('Hello, world!')
}
doSomething()
```

- Use variables: Declare a variable using the var keyword and assign it a value. Then, print the value of the variable to the console.

### Explore more advanced concepts

As you become more comfortable with the basics of JavaScript, you can start exploring more advanced concepts such as objects, arrays, and classes. There are many resources available online to help you learn these concepts, including online tutorials, video courses, and books.

### Conclusion

Congratulations on completing this beginner's guide to onboarding to JavaScript! With the knowledge and tools you've gained, you're well on your way to becoming a proficient JavaScript programmer. Keep practicing and learning, and soon you'll be building dynamic and interactive websites with ease.
