Making Decisions with Conditionals

Sometimes, you want your code to make choices. That's where if statements come in!

let temp = 25;
if (temp > 30) {
  alert("It's hot!");
} else {
  alert("It's not so hot.");
}

Doing Things Repeatedly: Loops

Loops let you run the same code multiple times, saving you from rewriting it over and over.

for (let i = 0; i < 5; i++) {
  console.log("Counting: " + i);
}

This prints numbers 0 to 4 in the console.

Why Use Control Flow?

• Make decisions based on data
• Repeat tasks efficiently

Real-World Uses

• Checking if a user has permission to access a page
• Looping through a list of messages to display them
