Conditional statements allow a program to make decisions based on different situations. Just like humans decide what to do based on conditions, JavaScript uses conditional statements to choose which code should run.
For example, a program can decide:
- If a user is logged in, show the dashboard
- If a password is wrong, show an error message
- If a score is high, show a success message
Without conditional statements, programs would always run the same code and could not respond to different inputs.
Why Conditional Statements Are Important
- They help programs make decisions
- They control the flow of execution
- They allow programs to respond to user actions
- They make applications smart and interactive
Every real-world application depends on conditions to work correctly.
In this example, JavaScript checks if the value of isUserLoggedIn is true. If it is, the message is displayed.
This shows how conditions allow programs to run code only when certain rules are satisfied.
Here, JavaScript runs different code depending on the condition. When hasAccess is false, the second message is shown.
This is how programs handle different outcomes based on conditions.
This example shows how conditional statements are used to make real-life decisions in programs.
By mastering conditional statements, students gain the ability to build smarter applications such as login systems, form validation, and dynamic content display.
