Nested Conditions


Nested conditions are used when one decision depends on another decision. This means an if statement is placed inside another if or else block.

Nested conditions help handle more complex situations where a single condition is not enough. They are commonly used in login systems, permission checks, and multi-step validations.

Learning nested conditions allows students to write programs that can handle real-life logic more accurately.

When to Use Nested Conditions

  1. When one condition depends on another 
  2. When checking multiple levels of permissions
  3. When validating input step by step
  4. When building multi-step decision logic 
  5. When handling detailed user flows  

Nested conditions make programs smarter but should be used carefully to keep code readable.

In this example, JavaScript first checks if the user is logged in. Only if that is true does it check whether the user is an admin.

This shows how one condition is evaluated inside another.

Here, the program first checks if the score is a pass mark. If it is, it then checks whether the performance is excellent or just good.

This kind of nested logic is often used in grading systems.

This example shows how nested conditions manage multiple decision levels in real-world scenarios like authentication systems.

By mastering nested conditions, students can write programs that handle complex logic and move closer to professional-level development.
