Find vs Map

Benchmark created on

Setup

// Setup
let specs = [];
let result = [];
let size = 1000; // adjust to 1000, 5000, etc.

for (let i = 0; i < size; i++) {
  let ref = Math.random().toString(36).substring(2, 15);
  specs.push({ reference: ref });
  result.push({ reference: ref, data: "data-" + i });
}

// Shuffle specs randomly
specs.sort(() => Math.random() - 0.5);

Teardown

specs = [];
result = []
