Body
<code>Object</code> is Eve, and <code>Function</code> is Adam, Adam (<code>Function</code>) uses his bone (<code>Function.prototype</code>) to create Eve (<code>Object</code>). Then who created Adam (<code>Function</code>)? -- The Inventor of the JavaScript language :-). According to utsaina's answer, I want to add more useful info. <blockquote> The most surprising thing for me was discovering that <code>Object.__proto__</code> points to <code>Function.prototype</code>, instead of <code>Object.prototype</code>, but I'm sure there's a good reason for that :-) </blockquote> It should NOT be. <code>Object.__proto__</code> should NOT point to <code>Object.prototype</code>. Instead, the instance of <code>Object</code> <code>o</code>, <code>o.__proto__</code> should point to <code>Object.prototype</code>. (Forgive me for using the terms <code>class</code> and <code>instance</code> in JavaScript, but you know it :-) I think the class <code>Object</code> itself is an instance of <code>Function</code>, that's why <code>Object.__proto__ === Function.prototype</code>. Therefore: <code>Object</code> is Eve, and <code>Function</code> is Adam, Adam (<code>Function</code>) uses his bone (<code>Function.prototype</code>) to create Eve (<code>Object</code>). Furthermore, even the class <code>Function</code> itself is an instance of <code>Function</code> itself, that is <code>Function.__proto__ === Function.prototype</code>, that's also why <code>Function === Function.constructor</code> Further furthermore, the regular class <code>Cat</code> is an instance of <code>Function</code>, that is <code>Cat.__proto__ === Function.prototype</code>. The reason for the above is, when we create a class in JavaScript, actually, we are just creating a function, which should be an instance of <code>Function</code>. <code>Object</code> and <code>Function</code> are just special, but they are still classes, while <code>Cat</code> is a regular class. As a matter of factor, in Google Chrome JavaScript engine, the following 4: <ul> <li><code>Function.prototype</code></li> <li><code>Function.__proto__</code></li> <li><code>Object.__proto__</code></li> <li><code>Cat.__proto__</code></li> </ul> They are all <code>===</code> (absolutely equal) to the other 3, and their value is <code>function Empty() {}</code> <pre><code>> Function.prototype function Empty() {} > Function.__proto__ function Empty() {} > Object.__proto__ function Empty() {} > Cat.__proto__ function Empty() {} > Function.prototype === Function.__proto__ true > Function.__proto__ === Object.__proto__ true > Object.__proto__ === Cat.__proto__ true </code></pre> OK. Then who creates the special <code>function Empty() {}</code> (<code>Function.prototype</code>)? Think about it :-)

1. COAgree with that, except for the last one thing: what is `function Empty() {}` you refer to being equal to Function.prototype, etc?, what is the code you used in chrome console?

2. COI corrected the last one thing that you pointed out. Their value is `function Empty() {}` in Google Chrome. I also added the console output.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
