How to use the json.ticks function in json

function profLogConvert ({isolateLogPath, pid, folder, stream}, args) {
  const { stdout, stderr, status } = spawnSync('node', ['--prof-process', '--preprocess', '-j', isolateLogPath])

  if (status !== 0) {
    args.log('prof isolateLogPath convert Failed: ', stderr + '', stdout + '')
    return
  }
  const json = isolateLogPath + '.json'
  fs.writeFileSync(json, stdout)
  const data = require(json)
  
  data.ticks.forEach((tick, i) => {
    // tick.ms = Math.round(tick.tm / 1000)
    const addr = tick.s.filter((n, i) => i % 2 === 0)
    const offsets = tick.s.filter((n, i) => i % 2 === 1)
    tick.stack = addr.map((n, i) => data.code[n]).filter(Boolean)
    tick.stack = tick.stack.filter(({type}) => type === 'JS')
    if (tick.stack.length === 0) {
      data.ticks[i] = undefined
      return
    }
  })

  data.ticks = data.ticks.filter(Boolean)

  const proc = 'node'
  const profName = 'cpu-clock'
  const space = '              '
