Casting

Cast (Aka. clone) allow to cast any object to class instance

Cast  allows to transform any object to class instance with all of the class functionalities including static methods and properties.
Usage
Interface
cast(classType, data, applyConstructor:boolean = false)
classInstance - The typeof class we want to cast to.
data -  The data should be cast.
applyConstructor - identify if constructor method should apply (default is false)
​
Using cast can be done in two ways:
Without applying the class constructor
In that case the data will cast into class instance but constructor method will not apply, which means auto populated properties won't initialize.
Example
post.class.ts
export class Post{
    title: string;
    body: string;
    creation: string = "11/11";
    owner: string;
​
    constructor(owner:string){
        this.owner = owner;
    }
    print(){
        console.log(`${this.title} - ${this.body} - ${creation}`);
    }
}
main.ts
import { cast } from "@sugoi/core";
​
const casted = cast(Post,{title:"wow",body:"Much body"});
// in that case creation and owner won't initialize
casted.print(); => "wow - Much body - undefined"
With applying the class constructor
In that case the data will cast into class instance and constructor method will apply, which means auto populated properties will initialize.
Example
post.class.ts
export class Post{
    title: string;
    body: string;
    creation: string = "11/11";
    owner: string;
​
    constructor(owner:string){
        this.owner = owner;
    }
    print(){
        console.log(`${this.title} - ${this.body} - ${creation}`);
    }
}
main.ts
import { cast } from "@sugoi/core";
​
const casted = cast(Post,{title:"wow",body:"Much body"});
// in that case creation and owner won't initialize
casted.print(); => "wow - Much body - 11/11"
