/**
 * Handsontable constructor.
 *
 * @core
 * @class Core
 * @description
 *
 * The `Handsontable` class (known as the `Core`) lets you modify the grid's behavior by using Handsontable's public API methods.
 *
 * ::: only-for react
 * To use these methods, associate a Handsontable instance with your instance
 * of the [`HotTable` component](@/guides/getting-started/installation/installation.md#_4-use-the-hottable-component),
 * by using React's `ref` feature (read more on the [Instance methods](@/guides/getting-started/react-methods/react-methods.md) page).
 * :::
 *
 * ::: only-for angular
 * To use these methods, associate a Handsontable instance with your instance
 * of the [`HotTable` component](@/guides/getting-started/installation/installation.md#5-use-the-hottable-component),
 * by using `@ViewChild` decorator (read more on the [Instance access](@/guides/getting-started/angular-hot-instance/angular-hot-instance.md) page).
 * :::
 *
 * ## How to call a method
 *
 * ::: only-for javascript
 * ```js
 * // create a Handsontable instance
 * const hot = new Handsontable(document.getElementById('example'), options);
 *
 * // call a method
 * hot.setDataAtCell(0, 0, 'new value');
 * ```
 * :::
 *
 * ::: only-for react
 * ```jsx
 * import { useRef } from 'react';
 *
 * const hotTableComponent = useRef(null);
 *
 * <HotTable
 *   // associate your `HotTable` component with a Handsontable instance
 *   ref={hotTableComponent}
 *   settings={options}
 * />
 *
 * // access the Handsontable instance, under the `.current.hotInstance` property
 * // call a method
 * hotTableComponent.current.hotInstance.setDataAtCell(0, 0, 'new value');
 * ```
 * :::
 *
 * ::: only-for angular
 * ```ts
 * import { Component, ViewChild, AfterViewInit } from "@angular/core";
 * import {
 *   GridSettings,
 *   HotTableComponent,
 *   HotTableModule,
 * } from "@handsontable/angular-wrapper";
 *
 * `@Component`({
 *   standalone: true,
 *   imports: [HotTableModule],
 *   template: ` <div>
 *     <hot-table [settings]="gridSettings" />
 *   </div>`,
 * })
 * export class ExampleComponent implements AfterViewInit {
 *   `@ViewChild`(HotTableComponent, { static: false })
 *   readonly hotTable!: HotTableComponent;
 *
 *   readonly gridSettings = <GridSettings>{
 *     columns: [{}],
 *   };
 *
 *   ngAfterViewInit(): void {
 *     // Access the Handsontable instance
 *     // Call a method
 *     this.hotTable?.hotInstance?.setDataAtCell(0, 0, "new value");
 *   }
 * }
 * ```
 * :::
 *
 * @param {HTMLElement} rootContainer The element to which the Handsontable instance is injected.
 * @param {object} userSettings The user defined options.
 * @param {boolean} [rootInstanceSymbol=false] Indicates if the instance is root of all later instances created.
