// Example:
console.log(sumArray([1, 2, 3, 4])); // 10



          

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

Best for learners
The best TypeScript playground I have used.
I've tried the official TS Playground and others, but this TypeScript playground has better features. Multi-file support, npm packages, and real IntelliSense. My go-to TypeScript IDE for quick experiments.
