/**
 * The `render` function takes target element, data, and optional insert options to render content in
 * the specified location on a web page.
 * @param {HTMLElement | string | null} target - The `target` parameter in the `render` function can be
 * either an HTMLElement, a string representing a selector, or null. It is the element to which the
 * data will be rendered.
 * @param {Node | string | (Node | string)[]} data - The `data` parameter in the `render` function can
 * accept a single Node or string, or an array of Nodes or strings.
 * @param options - The `options` parameter in the `render` function allows you to specify how the data
 * should be inserted into the target element. It has a property `insert` which can have two possible
 * values:
 * @returns The `render` function returns nothing (`undefined`) explicitly, as there is no `return`
 * statement with a value specified in the function. The function performs operations on the `target`
 * element based on the provided `data` and `options`, but it does not return any specific value.
