Why importing from the same file?

[zeritonius]

What are the benefits of importing from the same file, please? I'm not familiar with this approach.

Example:
https://github.com/vuejs/petite-vue/blob/main/src/directives/effect.ts

import { Directive } from '.'
import { execute } from '../eval'
import { nextTick } from '../scheduler'

export const effect: Directive = ({ el, ctx, exp, effect }) => {
  nextTick(() => effect(() => execute(ctx.scope, exp, el)))
}

Thank you.

It's not importing from the same file, but from the same directory, so that import could also look like:

import { Directive } from './index'

but shorter

Thank you so much for clarifying this.
