How do I sort React state without corrupting its previous order?
KitForma editorial guide. Array.sort changes its receiver.
Step-by-step answer
Array.sort changes its receiver. Use
setRows(old => [...old].sort((a,b) => a.score-b.score)), or toSorted where your target supports it. Copying the array does not clone the objects inside; editing a row also requires copying that row. Verify ascending and descending toggles and confirm another component holding the original array keeps its original order. Supply a numeric comparator for numeric fields.Sources and verification
