Can Cursor rewrite a function to be more functional instead of procedural?
Asked on Oct 16, 2025
Answer
Cursor can assist in refactoring procedural code into a more functional style by suggesting transformations that emphasize immutability and pure functions. This feature is typically accessed through the refactoring tools or suggestions within the Cursor environment.
<!-- BEGIN COPY / PASTE -->
// Original procedural code
function sumArray(arr) {
let sum = 0;
for (let i = 0; i < arr.length; i++) {
sum += arr[i];
}
return sum;
}
// Refactored functional code
const sumArray = arr => arr.reduce((acc, curr) => acc + curr, 0);
<!-- END COPY / PASTE -->Additional Comment:
- Functional programming emphasizes the use of pure functions and avoids shared state and mutable data.
- Cursor can help identify parts of your code that can be transformed into functional equivalents, often using higher-order functions like map, filter, and reduce.
- Refactoring to functional style can improve code readability and maintainability.
