How to add the item all to the filter?

Question

JavaScript

How to write a filter? here they helped me with the filter, but how to correctly add "all" to the array of filters, so that when you click on everything, the rest of the filters are reset and vice versa, when you click on any other, the all button goes out

Answer 1

You can make a computed property with a setter:

computed: {
  all: {
    get() {
      return this.filters.every(n => n.active);
    },
    set(val) {
      this.filters.forEach(n => n.active = val);
    },
  },
},

<label>
  <input type="checkbox" v-model="all">
  ALL
</label>
