Tests:

Build function
const buildData = () => makeExampleData(); for (let i = 0; i < 100; i += 1) { const newData = buildData(); }
New function, no cache
for (let i = 0; i < 100; i += 1) { const json = JSON.stringify(makeExampleData()); const newData = new Function('json', `return json`)(json); }
New function, cached data
const data = makeExampleData(); for (let i = 0; i < 100; i += 1) { const json = JSON.stringify(data); const newData = new Function('json', `return json`)(json); }
New function, cached stringify
const json = JSON.stringify(makeExampleData()); for (let i = 0; i < 100; i += 1) { const newData = new Function('json', `return json`)(json); }
JSON stringify & parse, no cache
for (let i = 0; i < 100; i += 1) { const json = JSON.stringify(makeExampleData()); const newData = JSON.parse(json); }
JSON stringify & parse, cached data
const data = makeExampleData(); for (let i = 0; i < 100; i += 1) { const json = JSON.stringify(data); const newData = JSON.parse(json); }
JSON stringify & parse, cached stringify
const json = JSON.stringify(makeExampleData()); for (let i = 0; i < 100; i += 1) { const newData = JSON.parse(json); }
