π Understanding control flow and loops is key to unlocking the full potential of JavaScript, enabling you to write efficient, dynamic applications. Let's explore these foundational concepts:
π Control Flow:
Control flow determines the order in which your code is executed. By default, JavaScript reads code from top to bottom, but with conditional statements, we can make it more dynamic! Hereβs a quick look:
let score = 85;
if (score >= 90) {
console.log("Excellent!");
} else if (score >= 75) {
console.log("Good job!");
} else {
console.log("Keep trying!");
}
π Loops:
Loops are powerful tools that help you execute a block of code multiple times, making tasks like iterating over arrays or repeating actions straightforward.
-
for
Loop: Perfect for running code a specified number of times.
let fruits = ["apple", "banana", "mango"];
for (let i = 0; i < fruits.length; i++) {
console.log(fruits[i]);
}
-
while
Loop: Runs as long as the specified condition is true.
let count = 0;
while (count < 5) {
console.log("Count is: " + count);
count++;
}
-
do...while
Loop: Similar towhile
, but guarantees at least one execution.
let number = 0;
do {
console.log("Number is: " + number);
number++;
} while (number < 3);
π Why It Matters:
Leveraging control flow and loops effectively can transform your code from good to great, making it more readable, efficient, and capable of handling complex tasks effortlessly.
