JavaScript Conditional Statements

 JavaScript Conditional Statements

JS conditional statements are fundamental programming constructs that allow you to make decisions in your code. They enable you to execute different blocks of code based on specified conditions. Conditional statements are crucial for adding logic and interactivity to your programs, making them respond dynamically to different situations.

Here are some common JS conditional statements:

1. `if` Statement:

The `if` statement executes a block of code if a specified condition is true.

Example:

In this code, the if statement checks if the age variable is greater than or equal to 18. If true, it prints "You are an adult"; otherwise, it prints "You are a minor."

2.`else if` Statement:

The `else if` statement allows you to specify multiple conditions to check.

Example:

Here, the code checks the temperature and provides different messages based on whether it's hot, pleasant, or cold outside.

3. `switch` Statement:

The `switch` statement is used for multi-case scenarios, where you have multiple conditions to check against a single value.

Example:

This code evaluates the `day` variable and provides a specific message based on the day of the week.

4. Ternary Operator (`?`):

The ternary operator is a concise way to write conditional statements.

Example:

This code sets the `weatherMessage` variable based on whether it's raining or not.

JS conditional statements are essential for controlling the flow of your program and making decisions based on various factors. They help create interactive and dynamic applications by allowing you to respond to user input, data, and changing circumstances. When using conditional statements, it's important to think through your logic carefully to ensure your code behaves as expected in different scenarios.
