Here is the sample with my json after JSON.parse().

{
  once: {
    version: '20.04',
    distributor: 'Ubuntu',
    cpu_num: 2,
    host_name: 'VM-12-3-ubuntu',
    user_name: 'root'
  },
  time: { allsec: 1755353, day: 20},
  mem: {
    total_mem: 2035212,
    used_mem: 572364,
    free_mem: 161520,
  },
  // these [Object] is what i want to parse
  cpu: { jiffies: [ [Object], [Object], [Object] ] },
  net: [
    { name: 'eth0', rx: [Object], Tx: [Object] }
  ]
}

How to make these [Object] to be parse ?
