js-tosorted-immutable

Use toSorted() instead of sort() to create a new sorted array without mutating the source. toSorted() returns a fresh array, keeping the original unchanged—essential for React state and props where mutations cause render bugs.

Yes, toSorted() accepts a comparator function. Pass a callback like (a, b) => a.name.localeCompare(b.name) to sort by specific object properties immutably.

sort() mutates the array in place, breaking React's immutability model and preventing re-renders when state changes aren't detected. toSorted() creates a new array, triggering proper state updates.

toSorted() requires modern JavaScript runtimes with Array.prototype.toSorted support. Check your build target and browser compatibility before using it in production React applications.

Yes, toSorted() works for any array stored in React state or passed as props—users, items, or other objects. Pass a comparator to sort by name, ID, or any property immutably.
