Benchmark: JSON.parse VS string.split2

Script Preparation code:

const testStringSplit = []
const testJSONParse = []
for (i = 0; i < 1000; i++) {
    testStringSplit.push(`${i},${i+1},${i+2}`)
    testJSONParse.push(`[${i},${i+1},${i+2}]`)
}

Tests:

JSON.parse
const testStringSplit = [] const testJSONParse = [] for (i = 0; i < 1000; i++) { testStringSplit.push(`${i},${i+1},${i+2}`) testJSONParse.push(`[${i},${i+1},${i+2}]`) } testJSONParse.forEach(x=>JSON.parse(x))
string.split
const testStringSplit = [] const testJSONParse = [] for (i = 0; i < 1000; i++) { testStringSplit.push(`${i},${i+1},${i+2}`) testJSONParse.push(`[${i},${i+1},${i+2}]`) } testStringSplit.forEach(x=>x.split(','))
