Performance Optimization Techniques

What performance optimization technique is implemented here?

// Before
const values = new Array(1000).fill(0);
values.forEach((_, i) => {
  values[i] = heavyComputation();
});

// After
const values = new Array(1000).fill(0);
const chunkSize = 50;
let index = 0;

function processChunk() {
  const end = Math.min(index + chunkSize, values.length);
  for (; index < end; index++) {
    values[index] = heavyComputation();
  }
  if (index < values.length) {
    setTimeout(processChunk, 0);
  }
}

Recursive optimization
Chunking and deferral
Chunking and deferral improves performance through: 1) Breaking large tasks into smaller, manageable chunks, 2) Yielding to the event loop between chunks, 3) Preventing UI blocking during heavy computations, 4) Better responsiveness in long-running operations, 5) Balancing processing time with UI updates, 6) Maintaining application responsiveness, 7) Efficient handling of large datasets, 8) Improved user experience during heavy processing.
