            // Task 1: Sum of All Elements in an Array
// Example:
console.log(sumArray([1, 2, 3, 4])); // 10
          

        


          

            // Hmm... Let me try
function sumArray(arr) {
    return arr.reduce((acc, curr) => acc + curr, 0);
}

The best React playground I have found.
I've tried CodeSandbox, StackBlitz, and others, but this React playground is the fastest. Hot reloading is instant, npm imports just work, and I can prototype React components in seconds. My go-to React sandbox now.
