Conditional Statements | Bondar Academy

Lesson Summary

This lesson covers conditional statements , which are essential for controlling the logic flow of applications. Conditional statements allow the application to execute different actions based on specific conditions, typically structured as: if (condition) { // execute this code } else { // execute this code } The if statement evaluates a condition inside parentheses. If the condition is true , the code block within the curly braces is executed; if false , the code in the else block runs. Example: Time-Based Greetings To illustrate conditional logic, we created a program that prints a greeting based on the current hour: If the hour is between 6 and 12, print "Good morning" . If the hour is between 12 and 18, print "Good afternoon" . Otherwise, print "Good evening" . The code snippet for this logic is as follows: if (hour >= 6 && hour = 12 && hour Example: Driver's License Eligibility Another example discussed was checking eligibility for a driver's license: if (age > 18 && isUSCitizen) { console.log("Customer is eligible for driver's license"); } else { console.log("Customer is not eligible for driver's license"); } In summary, conditional statements are crucial for managing the flow of execution in programming. They allow for complex decision-making by combining multiple conditions using else if and else statements.
