    {
      "*": [
        {
          "-": [
            {
              "var": "length"
            },
            2.2
          ]
        },
        3

    {
      "*": [
        10,
        3

// or reversely
console.log(parse(

  "-": [
    {
      "*": [
        {
          "-": [
            {
              "var": "length"
            },
            2.2
          ]
        },
        3
      ]

        10,
        3
