Question

Why do we use if statements in JavaScript?



- To break out of some block of code


- To do something only if a condition is true


- To do something while a condition is true


- To repeat something for a fixed number of times

Answer 1

In JavaScript, we use `if` statements primarily **to do something only if a condition is true**.

Here's a brief overview of the options you provided:

- **To break out of some block of code**: This can be done with statements like `break` or `return`, but not with `if` statements.

- **To do something only if a condition is true**: This is the primary use of `if` statements. They allow the code to execute a certain block only when the specified condition evaluates to true.

- **To do something while a condition is true**: This is typically accomplished using loops such as `while` or `for`, not `if` statements.

- **To repeat something for a fixed number of times**: This is usually done with loops such as `for` or `while`, rather than with `if` statements.

In summary, the correct answer is: **To do something only if a condition is true**.
