How to filters array and loop V-for in Vue.js

Question

I am trying to loop an array levels using Vue.js, I could to get the response json in actions with function forEach like:

  let filters = []
            const array = response.data
            array.forEach((element) => {
               filters.push(element)
            })

then stored data in state, there any way to filter by TYPE and then loop Data somehow to render in a select, data...etc. using V-for in Vue.js?

My json file:

     [
  {
    'type': 'filter',
    'datatype': 'str',
    'data': [
      {
        'var_name': 'Gender',
        'options': [
          'Male',
          'Female'
        ]
      }
    ]
  },
    {
      'type': 'filter',
      'datatype': 'date',
      'data': [
        {
          'var_name': 'From',
          'options': []
        }
      ]
    },
    {
      'type': 'range',
      'datatype': 'date',
      'data': [
        {
          'var_name': 'From',
          'options': []
        },
        {
          'var_name': 'To',
          'options': []
        }
      ]
    }
  ]

<div v-for="filter in filters">... </div>

computed: {
    filters() {
        return this.data.filter(item => item.type === 'filter')
    }
}

You can use below code in .vue file.

save your above filters array to data variable in vue file.

data() {
   return {
      filters: []
   }
}

const array = response.data;

array.forEach((element) => {
   this.filters.push(element);
})

and in html template use v-for like below.

<template v-for="oneItem in filters.filter(item => {item.type == 'filter'})"> 
</template>

I would suggest wrapping this filtered list inside a computed property, they are cached which will make your code faster as long as you don't change the original list.
