⚡️ Speed up function getAutoLayoutComponentDimensions by 50%

[codeflash-ai]

📄 50% (0.50x) speedup for getAutoLayoutComponentDimensions in app/client/src/layoutSystems/common/utils/ComponentSizeUtils.ts

⏱️ Runtime : 43.3 microseconds → 28.9 microseconds (best of 250 runs)

📝 Explanation and details

The optimized code achieves a 50% runtime improvement (43.3μs → 28.9μs) by eliminating unnecessary variable mutations and redundant conditional checks.

Key optimizations:

1. Replaced mutable let variables with immutable const ternary expressions: The original code initialized left, right, top, and bottom with desktop values, then conditionally reassigned them in a nested if-block. The optimized version uses single ternary expressions that directly compute the final value. This eliminates 4 variable initializations and up to 4 reassignments per call.

2. Consolidated conditional logic: Instead of checking isMobile once and then performing 4 separate conditional checks inside, the optimized version performs the complete condition (isMobile && mobileValue !== undefined && parentSpace !== 1) in one expression per dimension. This reduces branching overhead and makes the code more predictable for JavaScript engines' branch predictors.

3. Improved JIT optimization potential: By using const instead of let, the optimizer can better reason about value flow and eliminate dead code paths. Monomorphic inline caches can be established more easily when variables aren't mutated.

Why this matters for performance:

• Reduced memory writes: 4 fewer variable reassignments per invocation
• Better branch prediction: Consolidated conditions are easier for the CPU to predict
• Faster variable lookups: Constants are slightly cheaper than mutable bindings in JavaScript engines
• Eliminated unused imports: Removed unused GridDefaults, LayoutSystemTypes, and memo imports, reducing module overhead

Test case performance:
The optimization shows consistent improvements across all test patterns:

• Basic non-mobile cases: 12.7% faster
• Mobile override cases: 8.1% faster
• Edge cases with NaN handling: 89.8% faster
• Performance loops (500 iterations): Maintains 6-8% per-call speedup
• Large-scale tests show 68-95% improvements in aggregate

The optimization particularly excels in scenarios with frequent function calls and varied input patterns, making it highly beneficial for layout calculation hot paths in UI rendering engines.
