Boolean values are used to represent true or false conditions in a program. They help JavaScript make decisions based on different situations.
Whenever you check if something is correct, allowed, or possible, you are using boolean logic. Conditions built with boolean values control how programs behave and which code runs.
Learning boolean values and conditions is the first step toward writing intelligent programs that can make decisions.
Where Boolean Values Are Used
- Checking if a user is logged in
- Verifying passwords
- Showing or hiding content
- Allowing or blocking actions
- Making decisions in programs
Every real application depends on boolean values to work correctly.
This example shows two boolean values: true and false. These values are commonly used to control program logic and user access in real applications.
Here, JavaScript checks a condition using a boolean expression. If the condition is true, one message is shown; otherwise, a different message appears.
This type of decision-making logic is used in forms, login systems, and many real-world applications.
This example shows how a comparison creates a boolean result. The variable passed stores either true or false based on the condition.
Understanding boolean values and conditions prepares you for advanced topics like loops, functions, and complex decision-making in programs.
