// Write a function that takes an array of numbers and returns the sum of the numbers. The numbers can be negative or non-integer. If the array does not contain any numbers then you should return 0.

// Examples
// Input: [1, 5.2, 4, 0, -1]
// Output: 9.2

// Input: []
// Output: 0

// Input: [-2.398]
// Output: -2.398

// Assumptions
// You can assume that you are only given numbers.
// You cannot assume the size of the array.
// You can assume that you do get an array and if the array is empty, return 0.
// What We're Testing
// We're testing basic loops and math operations. This is for beginners who are just learning loops and math operations.
// Advanced users may find this extremely easy and can easily write this in one line.

// Sum Numbers
function sum (numbers) {
    let total = 0
    numbers.forEach(element => {
        total += element
    });
    return total
};
