Introduction to Conditional Statements

Conditional statements are used in programming to make decisions based on certain conditions. They allow us to control the flow of the program and execute specific statements or blocks of code based on whether a condition is true or false.

In JavaScript, the most common conditional statement is the if statement. It allows you to specify a condition inside parentheses, and if that condition evaluates to true, the code block inside the curly braces will be executed. Here's an example:

1// Using an if statement to check if a number is positive
2const number = 5;
3
4if (number > 0) {
5  console.log('The number is positive');
6}

In this example, we check if the number variable is greater than 0. If it is, we print a message to the console saying that the number is positive.

Conditional statements are the building blocks of decision-making in programming and are essential for creating dynamic and interactive applications. In the upcoming lessons, we will explore different types of conditional statements and learn how to use them effectively.
