Performance Optimization Techniques

What optimization strategy is demonstrated here?

// Before
const result = expensiveFunction();
if (result) {
  // use result
}

// After
let result;
if (condition) {
  result = expensiveFunction();
  // use result
}

Variable hoisting
Lazy evaluation
Lazy evaluation improves performance by: 1) Delaying expensive operations until needed, 2) Preventing unnecessary computations, 3) Reducing initial execution time, 4) Optimizing resource usage, 5) Only computing values when they're actually used, 6) Particularly useful for expensive function calls, 7) Improving application startup time, 8) Better resource utilization in conditional flows.
