Push values in an array from an array of objects

I have an array of object as follows. I want to basically loop through the projects.current_result and get all the values.

let data = [
    {
        vertical_name: "CORE",
        projects: [
            {
                name: "Alpha",
                id: 187,
                current_result: {
                    success: 0,
                    failure: 0,
                    skip: 0,
                    untested: 100
                }
            }
        ]
    },
    {
        vertical_name: "release",
        projects: [
            {
                name: "Beta",
                id: 27,
                current_result: {
                    success: 50,
                    failure: 20,
                    skip: 36,
                    untested: 0
                }
            },
            {
                name: "Charlie",
                id: 47,
                current_result: {
                    success: 37,
                    failure: 25,
                    skip: 40,
                    untested: 0
                }
            }
        ]
    }
  ]

for e.g. i want to get success values of each of the projects and put all of those values in an array. So in this case success= [0,50,37] Similarly, i want to put values for failure, skip and untested

failure=[0,20,25]
skip=[0,36,40]
untested=[100,0,0]

I tried achieving that with below code but somehow i am not able to get desired result. Any advice on how to correct this code please

let alteredResponse = data.forEach(prj => { 
     prj.reduce((result, {
    count
  }) => {
    result.success.push(count.success|| 0);
    result.failure.push(count.failure || 0);
    result.skip.push(count.skip || 0);
    result.untested.push(count.untested || 0);
    return result;
  }, {
    success: [],
    failure: [],
    skip: [],
    untested: []
  })
  });

const data = [
  {
    vertical_name: 'CORE',
    projects: [
      {
        name: 'Alpha',
        id: 187,
        current_result: {
          success: 0,
          failure: 0,
          skip: 0,
          untested: 100
        }
      }
    ]
  },
  {
    vertical_name: 'release',
    projects: [
      {
        name: 'Beta',
        id: 27,
        current_result: {
          success: 50,
          failure: 20,
          skip: 36,
          untested: 0
        }
      },
      {
        name: 'Charlie',
        id: 47,
        current_result: {
          success: 37,
          failure: 25,
          skip: 40,
          untested: 0
        }
      }
    ]
  }
];

const result = {
  success: [],
  failure: [],
  skip: [],
  untested: []
};
data.forEach((prj) => {
  prj.projects.reduce((_, { current_result }) => {
    result.success.push(current_result.success || 0);
    result.failure.push(current_result.failure || 0);
    result.skip.push(current_result.skip || 0);
    result.untested.push(current_result.untested || 0);
    return result;
  }, result);
});

console.log(result);

You can achieve this with two forEach

Logic

Loop though each nodes in data
Loop through each nodes in projects from the nodes in data
Push success, failure, skip, untested nodes from project node to respective result node.

Working Fiddle

const data = [{"vertical_name":"CORE","projects":[{"name":"Alpha","id":187,"current_result":{"success":0,"failure":0,"skip":0,"untested":100}}]},{"vertical_name":"release","projects":[{"name":"Beta","id":27,"current_result":{"success":50,"failure":20,"skip":36,"untested":0}},{"name":"Charlie","id":47,"current_result":{"success":37,"failure":25,"skip":40,"untested":0}}]}];

const result = {
  success: [],
  failure: [],
  skip: [],
  untested: [],
}

const alteredResponse = data.forEach(prj => {
  prj.projects.forEach((project) => {
    result.success.push(project.current_result.success);
    result.failure.push(project.current_result.failure);
    result.skip.push(project.current_result.skip);
    result.untested.push(project.current_result.untested);
  })
});
console.log(result);

You could try this approach

first map to get the projects
flatten the projects
map the projects to get the current_results
reduce to combine all the results into one final object

let data = [ { vertical_name: "CORE", projects: [ { name: "Alpha", id: 187, current_result: { success: 0, failure: 0, skip: 0, untested: 100, }, }, ], }, { vertical_name: "release", projects: [ { name: "Beta", id: 27, current_result: { success: 50, failure: 20, skip: 36, untested: 0, }, }, { name: "Charlie", id: 47, current_result: { success: 37, failure: 25, skip: 40, untested: 0, }, }, ], }, ]

const res = data
  .map(({ projects }) => projects)
  .flat()
  .map(({ current_result }) => current_result)
  .reduce((acc, el) => {
    for (const [key, value] of Object.entries(el)) {
      if (!acc[key]) {
        acc[key] = [value]
      } else {
        acc[key].push(value)
      }
    }
    return acc
  }, {})

console.log(res)
