Conditional statements are used in programming to perform different actions based on whether certain conditions are met or not. This allows control and decision making in the execution of the program. JavaScript has several different types of conditional statements, but the most common ones are if statements and switch statements.

if statements are used to check if a certain condition is true and to execute specific code accordingly. For example, you can use if statements to check if a variable is equal to another:

This checks if the variables "x" and "y" are equal. If they are, the code executes the first sentence, otherwise the second sentence.

Switch statements are used to check the value of a variable and execute code based on it. For example, you can use switch statements to check which day of the week it is:

This checks which day of the week it is using the variable "paiva". Different case statements are used in the switch statement to check which day corresponds to the given value. If the day corresponds to a case statement, the code executes that statement and then stops. If no case statement corresponds to the given value, the default statement is executed.

Using conditional statements gives you the opportunity to make decisions during program execution and gives you greater control over how the program works.

## if statements

if statements are used to check if a certain condition is true and to execute specific code accordingly. For example, you can use if statements to check if a variable is equal to another:

```javascript
var x = 5;
var y = 10;
if (x == y) {
  console.log("Variables are equal");
} else {
  console.log("Variables are not equal");
}
```

This checks if the variables "x" and "y" are equal. If they are, the code executes the first sentence, otherwise the second sentence.

Switch statements

Switch statements are used to check the value of a variable and execute code based on it. For example, you can use switch statements to check which day of the week it is:

```javascript
var day = 4;
switch(day) {
  case 1:
    console.log("Monday");
    break;
  case 2:
    console.log("Tuesday");
    break;
  case 3:
    console.log("Wednesday");
    break;
  case 4:
    console.log("Thursday");
    break;
  case 5:
    console.log("Friday");
    break;
  case 6:
    console.log("Saturday");
    break;
  case 7:
    console.log("Sunday");
    break;
  default:
    console.log("Invalid value");
}
```

This checks which day of the week it is using the variable "paiva". Different case statements are used in the switch statement to check which day corresponds to the given value. If the day corresponds to a case statement, the code executes that statement and then stops. If no case statement corresponds to the given value, the default statement is executed.

JavaScript Conditional Statements

This course is an introduction to web development and focuses on the basics of HTML, CSS, JavaScript and backend systems. The aim of the course is to provide students with the necessary skills and knowledge to design, develop and understand simple web applications.

This course is an introduction to web development and focuses on the basics of building websites, namely HTML, CSS, JavaScript, and fundamentals of backend systems. The goal of the course is to provide you with the necessary skills and knowledge to design and develop simple full-stack web applications, as well as understand web applications made by others.

In the first part, HTML is studied, which is a markup language used in building websites.


The second part covers the basics of CSS, such as the use of style sheets, rules, selectors, and formatting. It also covers advanced features of CSS, such as animations and responsive design.

In the third part, we will study JavaScript, which is currently an incredibly important tool in both frontend and backend development, and thus also in cybersecurity and ethical hacking.

In the final part, we will learn how to build back-end systems using the Python Flask framework. You will learn the basics of back-end systems, such as using databases, authentication, session management, and access control.

You can do the course exercises on your own computer if you want, but each code example has a button that allows you to directly run the code in the browser and see what the page looks like or what the script prints. So you do not need to install anything, but you can if you want.

It is recommended but optional to create an account on replit.com service. In that case, you can just click "Fork" on the code examples to make a copy for yourself to play with
