Execution Comparison

Compare different approaches to the same problem — see how execution paths, memory usage, and performance differ side by side.

Run History

All stored executions. Select two to compare.

Click a run to select it as Run A or Run B for comparison.

Sum 1-5 (for loop)

10 events · 1 outputs

let sum = 0;
for (let i = 1; i <= 5; i++) {
  sum += i;
}
console.log(sum);

Sum 1-5 (while loop)

15 events · 1 outputs

let sum = 0;
let i = 1;
while (i <= 5) {
  sum += i;
  i++;
}
console.log(sum);

Sum 1-3 (reduce)

7 events · 1 outputs

const arr = [1, 2, 3];
const sum = arr.reduce((a, b) => a + b, 0);
console.log(sum);
