Optimize algorithms by eliminating redundant work and intermediate data structures. Look for opportunities to use lazy evaluation, conditional execution, and more efficient operations.
Key strategies:
Examples:
// Instead of always creating intermediate arrays:
const materialized = [...stream()].map(materializeNodeRelationships);
// Use imperative style to avoid extra allocations:
const materialized: Node[] = [];
for (const n of stream()) {
materialized.push(materializeNodeRelationships(n));
}
// Conditional predicate application:
const matchesConstraintAndFilters = predicate
? (row: Row) => matchesConstraint(row) && predicate(row)
: matchesConstraint; // Avoid wrapping when unnecessary
// Use efficient built-ins:
yield* sorted.slice(0, k); // Instead of manual loop
This approach improves performance by reducing computational overhead, memory allocations, and unnecessary operations while maintaining code correctness.
