Filtering on vue js?

Question

Vue.js

Hello, I've been struggling for an hour, I don't understand how to do it.

There is a field for filtering:

<input type="text" v-model="searchList" placeholder="Выберите фильтр" />

computed: {
  	listFilter() {
      return this.filter1.filter(item => item.indexOf(this.searchList) !== -1)
    },
  	filter1(){
    	return ['bmw', 'audi', 'ford']
    },
    filter2(){
    	return [2017, 2018, 2019]
    },
    filter3(){
    	return ['седан', 'купе', 'хетчбек']
    }
  },

How can filters be combined?
So that the filter was first by brand, then by year, and then by type?

Answer 1

[...this.filter1(),...this.filter2(),...this.filter3()].filter()
