## JavaScript Conditional Statements
There are mainly three types of conditional statements in JavaScript.
1. **if Statement**: An ‘if’ statement executes code based on a condition.
2. **if…else Statement**: The if…else statement consists of two blocks of code; when a condition is true, it executes the first block of code and when the condition is false, it executes the second block of code.
3. **if…else if…else Statement**: When multiple conditions need to be tested and different blocks of code need to be executed based on which condition is true, the if…else if…else statement is used.
## How to use Conditional Statements
Conditional statements are used to decide the flow of execution based on different conditions. If a condition is true, you can perform one action and if the condition is false, you can perform another action.

lines of code to be executed if condition2 is true
}
else
{
