get the Swiper instance in components inside of Swiper

setup() {
  const swiper = ref();

  return {
    swiper,
    onSwiper: instance => swiper.value = instance,
    ...
  };
},

<swiper
  @swiper="onSwiper"
  ...
>

...
const category = categories.value.find((c: CategoriesInterface) => c.id === record.categoryId);
...
return {
  ...
  categoryName: category ? category.title : 'default name'
  ...
}

type UpdateDataActions = {
  commit: string;
  getters: (() => void)[];
  rootGetters: (() => void)[];
}
... async updateData({commit,getters,rootGetters}:UpdateDataActions, toUpdate: string) {...}

When using TypeScript, the key can be a symbol casted as InjectionKey - a Vue provided utility type that extends Symbol, which can be used to sync the value type between provide() and inject().

import {InjectionKey} from 'vue';
// InjectionKey<T>, где T представляет явно передаваемый тип,  который отслеживается при provide/inject
export const localizeFilterKey: InjectionKey<(key: string) => string> = Symbol();

import localizeFilterKey from '@/injection-keys'
...
    app.provide(localizeFilterKey, localizeFilter)
...

import localizeFilterKey from '@/injection-keys'
...
    const messagePlagin = inject(localizeFilterKey);
...

if (interval.value) {
  clearInterval(interval.value);
}

{
 1:  'Вася',
 2:  'Петя',
 3:  'Маша',
}

Быстрее ли поиск в Map чем поиск в обычном массиве?

{
  title: data.title,
  deadLineTimestamp: new Date(data.deadLine).getTime(),
  description: data.description,
}

let date =  new Date(893074920000); 
console.log(date);
