Benchmark: json stringify vs object tostring number thresholds

Script Preparation code:

function makeTestDataNum() { return 0; }

function makeTestDataUndef() { return undefined; }

function makeTestDataArray() { return [0, 0.4, 0.6, 1]; }

Tests:

toString number
const d = makeTestDataNum() d ? d.toString() : "0"
JSON.stringify number
JSON.stringify(makeTestDataNum());
toString undefined
const d = makeTestDataUndef() d ? d.toString() : "0"
JSON.stringify undefined
JSON.stringify(makeTestDataUndef());
toString array
const d = makeTestDataArray() d ? d.toString() : "0"
JSON.stringify array
JSON.stringify(makeTestDataArray());
