IF, Else, and Else IF Statements in JavaScript

In the vast landscape of JavaScript, making decisions is a fundamental skill. That’s where IF, Else, and Else IF statements come into play. These are like traffic signals for your code, directing it based on conditions. Whether you need your code to take one path if a condition is true and another if it’s false, or navigate through multiple possibilities, these statements are your coding compass. Let’s explore the world of IF, Else, and Else IF statements and learn how they empower your code.

Decisions are at the heart of coding. You might want your code to behave differently based on user input, the time of day, or various other factors. That’s where IF statements shine. They allow your code to make decisions, executing different blocks of code based on whether a condition is true or false.

List of Statements

1. IF Statement

The IF statement is your go-to for simple decision-making. If the condition is true, the specified code executes.

let temperature = 25;

if (temperature > 30) {
  console.log('It\'s a hot day!');
}

2. Else Statement

The ELSE statement complements the IF statement. If the condition in IF is false, the code within ELSE executes.

let temperature = 25;

if (temperature > 30) {
  console.log('It\'s a hot day!');
} else {
  console.log('It\'s a moderate day.');
}

3. Else IF Statement

When you have multiple conditions to consider, the ELSE IF statement comes to the rescue. It allows you to check additional conditions if the initial IF condition is false.

let temperature = 25;

if (temperature > 30) {
  console.log('It\'s a hot day!');
} else if (temperature > 20) {
  console.log('It\'s a warm day.');
} else {
  console.log('It\'s a cold day.');
}

Conclusion

IF, Else, and Else IF statements are your code’s traffic signals, helping it navigate through different scenarios. As you incorporate these decision-making tools into your coding repertoire, your ability to create dynamic and responsive programs will flourish.

Happy coding!

With IF, Else, and Else IF statements, your code becomes a savvy navigator, adapting to various conditions effortlessly.
