You finished all the chapters! This is very wonderful! Let's now consolidate the information you learned during the course and take a quiz.

# Literals, Variables, Constants
- **Literal** is a value in the code.
- **Variable** (`let`) is named storage of value (literal) for the multiple usages.
- **Constant** (`const`) is an unchangeable variable.

# Data Types
- **number** is a numeric data type.
- **string** is a text data type. Writing in quotes (`"` or `'`).
- **boolean** is a logical data type (`true` or `false`).
- **array** is a collection of values. The most usable methods is `push()`, `pop()`, `unshift()` and `shift()`.

# Basic operations
- Assignment (`=`).
- Math (`+`, `-`, `*`, etc.).
- Comparison (`>=`, `<`, `==`, `===`, etc.).
- Logical (AND `&&`, OR (`||`).
- String Concatenation (`+` between strings).

# Conditional Statements
- `if (condition) {code block}`
- `else {code block}` after `if`.
- `else if (condition) {code block}` for a few conditions.

# Loops
- `while (condition) {code block}`.
- `do (code block) while (condition)`.
- `for (let counter; condition; counter++) {code block}`.

# Functions
- `function myFunc(arg1, arg2, arg3) {code block}`
- Call the function: `myFunc(value1, value2, value3)`
- Use the `return` keyword to return the value from a function.

First, let's get acquainted with JavaScript and look at its syntax. In this section, you will get a basic familiarity with the JavaScript syntax to make it easier to learn in detail later on.

Now it's time to learn about the data types that JavaScript works with. We'll start by looking at the difference between literals and variables, and then delve into the various data types.

We have become familiar with the various data types. Now, let's learn how to work with them by learning the operations we can perform with each data type.

Next, we will learn how to control the flow of execution. It's a straightforward process: we can tell the interpreter exactly what to do under certain conditions.

Next, we will explore how to shorten code using repetitive looped actions. We will examine the types of loops available in JavaScript and learn how to work with them.

Finally, to be able to write simple programs, we need to learn about functions that can make our lives much easier. We will learn how to create and use our functions.
