📘 Introduction to Algorithms with JavaScript – Beginner-Friendly Guide

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:

1. Assume the first element is the largest
2. Loop through the array
3. Compare each number to the current max
4. If a number is greater, update the max

Simple, right?
