**Arrow functions** are a new addition to JavaScript that let us create inline functions without using the `function` and `return` keywords. They are simply a shorter syntax version of the normal JavaScript functions.
JavaScript function:

let myFunc = function () {
    return 1 + 6;
}
console.log(myFunc());

```js
let myFunc = () => {
    return 1 + 6;
}
```

If the function has only one statement and returns a value, then we can remove the braces and the return keyword, hence the resultant code will be:

We can also pass arguments in the ES6 inline functions, using the syntax:

let myFunc = (a, b) => a + b
console.log(myFunc(5, 4));

## Task

Create an inline function named `threeProduct` that takes in three numbers / arguments namely `a`, `b`, `c`, and returns the product of those numbers. 
Call the function inside a console.log function and pass `1`, `2` and `9` as arguments.


In this course, we will learn how to use the JavaScript React library for making front-end applications. This course will help you understand the structure of a React application, how to add it to an existing website, and how to set up a React app from scratch. You will learn how to easily create React applications and expand them further for more advanced purposes. This course is intended for beginners though basic knowledge of JavaScript is required.

In this section we will explore why React is useful and why it is worth learning it at all. We will also learn one prerequisite, ES6, which will be used throughout the course.

In this section, we will learn another prerequisite - JSX which will be used throughout the course. Finally, we will explore some example code to get acquainted with React.

In this section we will learn about the essential and practical parts of React excluding the components – which will be covered in the next section. We will look at how JSX can be used with React, and how to create and render more complex elements in the React DOM using JSX. We will also learn how to set up a React based project, and we will explore its structure for deepening our understanding.

In this section you’ll be introduced to React components. We will look at what React components are and why we need them. We will explore the two different types of React components and learn the syntax for creating them. We will use them to create a single page application that displays X.

In this section we will learn more about how to combine JavaScript and JSX to create dynamic content. We will also learn how to pass data between components. In the end we will also explore event handling.

In the end of the previous chapter, we tried making a Todo application though in our attempt to do so we soon discovered that we needed some method for re-rendering the components once the data is updated in a component as React wasn’t automatically doing that for us. In this section we will learn how to fix such issues using ‘Hooks’. We will learn and implement hooks in detail. By the end of this section, you will be able to create stateful components in React and combine them to create complex web applications.

In this chapter we will learn how to add different pages to our React application and render different components based on URL. You will gain sufficient knowledge to be able to create multi-page applications.
