Implement dedicated fast paths for common search patterns while maintaining a complete fallback path for edge cases. This optimization pattern significantly improves performance for frequent operations while ensuring correctness for all scenarios.
Key implementation guidelines:
- Identify the most common usage patterns
- Create type-specific or pattern-specific fast paths
- Maintain a complete fallback path for edge cases
- Consider adding configuration options for traversal depth
Example:
function optimizedSearch(values, target) {
// Fast path for primitive type comparisons
if (typeof target === 'number' || typeof target === 'string') {
return values.includes(target)
}
// Fast path for same-type objects
if (values.some(v => typeof v === typeof target)) {
return values.some(v => String(v) === String(target))
}
// Fallback path for complex comparisons
return values.some(v => looseEqual(v, target))
}
This pattern is especially valuable in framework code where the same operations are performed frequently. The fast paths handle common cases efficiently while the fallback ensures correctness for all scenarios.
