jQueryオブジェクト初期化のパラメータ伝達方式

jQueryオブジェクトの初期化のパラメータ伝達方法は、次のとおりです.
1.$(DOMElement) 2.$('...'),$('#id'),$('.class')は文字列を入力します.これは最も一般的な形式です.このパラメータは、contextパラメータが$(...)であることもよくあります.DOMElement 3.$(function() {}); <===> $(document).ready(function() { }); 4.$({selector : '.class', context : context}) <===> $('.class', context)

jQuery.fn = jQuery.prototype = {
  constructor: jQuery,
  init: function( selector, context, rootjQuery ) {
    var match, elem, ret, doc;
    //   $(""), $(null), $(undefined), $(false)     ,    this
    if ( !selector ) {
      return this;
    }
    //    selector DOM   , context  selector
    if ( selector.nodeType ) {
      this.context = this[0] = selector;
      this.length = 1;
      return this;
    }
    // Handle HTML strings
    //     selector       ,
    if ( typeof selector === "string" ) {
      if ( selector.charAt(0) === "" && selector.length >= 3 ) {
        // Assume that strings that start and end with <> are HTML and skip the regex check
        match = [ null, selector, null ];
      } else {
        match = rquickExpr.exec( selector );
      }
      // Match html or make sure no context is specified for #id

            this.length = 1;
