Algorithms are the heart of programming. Whether you're building a simple app or a complex system, knowing how to write and understand algorithms is key to becoming a better developer.
In this post, we’ll break down the basics of algorithms and walk through how to write your very first one using JavaScript.

🧠 What is an Algorithm?
An algorithm is a set of step-by-step instructions used to solve a problem or perform a task.
Think of it like a recipe: a clear list of actions you follow to achieve a result.
Example: To make tea, you boil water, add tea leaves, let it steep, then pour into a cup.
In programming, algorithms help us solve tasks like sorting numbers, searching data, or processing input.
🛠️ Why Learn Algorithms?
Learning algorithms will help you:
- ✅ Improve your problem-solving skills
- ✅ Write efficient code
- ✅ Prepare for technical interviews
- ✅ Build scalable and optimized applications
💻 Writing Your First Algorithm in JavaScript
Here’s a simple example of an algorithm that finds the largest number in an array:
function findMax(arr) {
let max = arr[0];
for(let i = 1; i < arr.length; i++) {
if(arr[i] > max) {
max = arr[i];
}
}
return max;
}
console.log(findMax([3, 9, 2, 5, 7])); // Output: 9
🔍 How it works:
- Assume the first element is the largest
- Loop through the array
- Compare each number to the current max
- If a number is greater, update the max
Simple, right?
