Structs

[GDenisC]

Reasons

• V8 optimizations
• Better minification and obfuscation
• Harder deobfuscation

Example 1

class Foo {
    constructor() {
        this.x = 1;
    }

    get x() {
        return this.x;
    }
}

console.log(new Foo().x);

function Foo_constructor() {
    /* or just return { x: 1 } */
    var self = {};
    self.x = 1;
    return self;
}

function Foo_get_x(self) {
    return self.x;
}

console.log(Foo_get_x(Foo_constructor()));

Example 2

class Foo {
    getHelloString() {
        return 'hello';
    }
}

class Bar extends Foo {
    getHelloString() {
        return super.getHelloString() + ' world';
    }
}

console.log(new Bar().getHelloString());

function Foo_getHelloString(self) {
    return 'hello';
}
function Bar_getHelloString(self) {
    return Foo_getHelloString(self) + ' world';
}
console.log(Bar_getHelloString({}));
