Sum of Array

Let's practice array operations by calculating the sum of all numbers in an array!

Your Task:

Create a function that takes an array of numbers and returns their sum. This fundamental operation is used everywhere in programming.

Examples:

• •[1, 2, 3] → 6 (1 + 2 + 3)
• •[10, 20, 30, 40] → 100
• •[5] → 5 (single element)
• •[] → 0 (empty array)

What You'll Learn:

• •How to iterate through arrays
• •Working with the reduce method
• •Handling edge cases (empty arrays)
• •Basic mathematical operations in loops

Pro Tip:

There are multiple ways to solve this - try using a for loop first, then explore array methods like reduce!
