      "DEVELOPMENT": 2895,
      "QUALITY ENGINEERING": 780,
      "OPERATION": 33175,

      "DATA": 15750
    }

  {
    "project": "RealWatch",
    "hours": {
      "OPERATION": 2490,
      "DATA SCIENCE": 810,

One-liner solution: Merge all data.hours into one object, then use Object.entries() to get the key value pair as a comma separated array.

var data = [{
    "project": "Sciera Internal Application",
    "hours": {
      "DATA SCIENCE": 3270,
      "DEVELOPMENT": 2895,
      "QUALITY ENGINEERING": 780,
      "OPERATION": 33175,
      "MARKET": 3935,
      "DATA": 15750
    }
  },
  {
    "project": "RealWatch",
    "hours": {
      "OPERATION": 2490,
      "DATA SCIENCE": 810,
      "QUALITY ENGINEERING": 26045,
      "DATA": 21340
    }
  },
]

const results = Object.entries(Object.assign({}, ...data.map(datum => datum.hours)));
console.log(results)
