Conditional Statements
Learn to use JavaScript conditional statements such as if, if-else, else-if, and switch to control program flow based on conditions. Understand how to create decision-making logic, handle multiple cases, and write clear, maintainable code for interactive web applications.
In JavaScript, conditional statements enable us to make decisions in our code by evaluating expressions and executing corresponding blocks of code. They help us create logic that reacts to different inputs or scenarios.
