What are @vue/babel-helper-vue-jsx-merge-props's main functionalities?

Merging Props

This feature allows you to merge multiple sets of properties into one. In the example, `props1` and `props2` are merged, resulting in a single object that combines the classes and other properties.

const mergeProps = require('@vue/babel-helper-vue-jsx-merge-props');
const props1 = { class: 'btn', type: 'button' };
const props2 = { class: 'btn-primary', disabled: true };
const mergedProps = mergeProps([props1, props2]);
console.log(mergedProps); // { class: 'btn btn-primary', type: 'button', disabled: true }

@vue/babel-helper-vue-jsx-merge-props

A package used internally by vue jsx transformer to merge props spread. It is required to merge some prop trees like this:

import mergeProps from '@vue/babel-helper-vue-jsx-merge-props'

const MyComponent = {
  render(h) {
    // original: <button onClick={$event => console.log($event)} {...{ on: { click: $event => doSomething($event) } }} />
    return h(
      'button',
      mergeProps([
        {
          on: {
            click: $event => console.log($event),
          },
        },
        {
          on: {
            click: $event => doSomething($event),
          },
        },
      ]),
    )
  },
}

This tool is used internally and there is no reason for you to ever use it.
