Hi, Michelle here! Today, let's dive into the world of program control flows in JavaScript, a fundamental concept that guides the order in which your code executes. Control flow statements like if-else, switch, loops (for, while, do-while), and conditional operators dictate how your program responds to different conditions and how it iterates through data. For example, if-else allows you to execute code based on certain conditions:

if (temperature > 30) {
  console.log("It's hot outside!");
} else {
  console.log("It's not so hot today.");
}

Adding loops into the mix, we can handle repetitive tasks efficiently:

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

Each control flow statement serves a unique purpose, enabling you to build more dynamic, responsive, and powerful web applications. Understanding and mastering these will significantly enhance your coding proficiency!
