The definition of the Object object includes it being a constructor. Despite this, I find myself able to execute methods such as Object.create(), Object.freeze(), and Object.assign() directly on it. Additionally, creating a new object using "var foo = new Object()" further solidifies these capabilities.
This ability to call methods directly on a constructor like Object has always been puzzling to me.
It's an interesting concept that I've never fully understood.
Constructors have the ability to have properties themselves, known as static methods in modern syntax. For instance:
class Foo {
static fooRelatedFn() {
console.log('foo related function running');
}
constructor() {
this.bar = 'bar';
}
}
Foo.fooRelatedFn();
const foo = new Foo();
console.log(foo.bar);The same concept can be achieved using traditional syntax by simply assigning to a property of the constructor:
function Foo() {
this.bar = 'bar';
}
Foo.fooRelatedFn = function() {
console.log('foo related function running');
}
Foo.fooRelatedFn();
const foo = new Foo();
console.log(foo.bar);Recently, I came across this fascinating website: As you scroll down, the images on the site gradually unveil more details, which caught my attention. This unique effect is not something commonly seen on websites, and I'm curious to learn how it is ...
