Question

Why do we use if/else statements in JavaScript?



- To repeat something for a fixed number of times


- To either do something if a condition is true or do something else


- To break out of some block of code


- To repeat something while a condition is true

Answer 1

In JavaScript, we use if/else statements primarily **to either do something if a condition is true or do something else**. This construct allows for decision-making in the code by evaluating a boolean condition and executing different blocks of code based on whether that condition is true or false.

Here's a breakdown of the options:

- **To repeat something for a fixed number of times**: This is usually achieved using loops (like `for`, `while`, etc.), not if/else statements.

- **To either do something if a condition is true or do something else**: This is the correct usage of if/else statements. They allow you to control the flow of your program based on specific conditions.

- **To break out of some block of code**: This is typically managed with control statements like `break` or `return`, rather than if/else statements.

- **To repeat something while a condition is true**: Again, this is done using loops (like `while` or `do...while`), not if/else statements.

So, the correct answer is **"To either do something if a condition is true or do something else."**
