Answer 1

您只需映射您的skills.extracted数组并完全按照您的描述构建结果:

var input = {
  skills: {
    extracted: [
      {value: 'PHP'},
      {value: 'JavaScript'},
      {value: 'Python'}
    ]
  }
}

var output = {
        children: [
            {
                name: 'skills',
                children2: input.skills.extracted.map(skill => ({name:skill.value}))
            }
       ]
    }
    
console.log(output);
