What is DSA?

DSA stands for Data Structures and Algorithms. Data structures decide how information is stored, while algorithms decide how it is processed.

Why DSA matters

• Write programs that handle larger inputs
• Choose an appropriate way to organize data
• Compare different solutions
• Build problem-solving and interview skills

Simple algorithm: find the largest value

function findLargest(numbers) {
  let largest = numbers[0];

  for (const number of numbers) {
    if (number > largest) largest = number;
  }

  return largest;
}
