How to construct an array of object to unique array of object

I have an array of object like this

let data = 
[
    {
        text: 'label'
    },
    {
        text: 'username'
    },
    {
        text: 'category'
    },
    {
        text: 'book'
    },
    {
        text: 'john'
    },
    {
        text: 'education'
    },
    {
        text: 'car'
    },
    {
        text: 'doe'
    },
    {
        text: 'automotive'
    },
    {
        text: 'shoes'
    },
    {
        text: 'cena'
    },
    {
        text: 'fashion'
    },
]

and my expect array of objects

let result = 
[
    {
        label: 'book',
        username: 'john',
        category: 'education'
    },
    {
        label: 'car',
        username: 'doe',
        category: 'automotive'
    },
    {
        label: 'shoes',
        username: 'cena',
        category: 'fashion'
    },
]

>Solution :

According to your data,the top 3 records are property name,others are data,so we can use Array.slice() to get the property names

Then we can use Array.reduce() to convert the left data

let keys = data.slice(0,3).map(v => v.text)
let result = data.slice(3).reduce((a,c,i) =>{
  let key = keys[i%3]
  if(i%keys.length ==0){
   let obj = {}
   obj[key] = c.text
   a.push(obj)
  }else{
   a.at(-1)[key]=c.text
  }
  return a
},[])

console.log(result)

let data = 
[
    {
        text: 'label'
    },
    {
        text: 'username'
    },
    {
        text: 'category'
    },
    {
        text: 'book'
    },
    {
        text: 'john'
    },
    {
        text: 'education'
    },
    {
        text: 'car'
    },
    {
        text: 'doe'
    },
    {
        text: 'automotive'
    },
    {
        text: 'shoes'
    },
    {
        text: 'cena'
    },
    {
        text: 'fashion'
    },
]

let keys = Object.values(data.slice(0,3)).map(v => v.text)
let result = data.slice(3).reduce((a,c,i) =>{
  let key = keys[i%3]
  if(i%keys.length ==0){
   let obj = {}
   obj[key] = c.text
   a.push(obj)
  }else{
   a.at(-1)[key]=c.text
  }
  return a
},[])

console.log(result)
