Run time decorate ( + JS support)

Apply decoration in run time

Overview
Apply run time decoration is strong advantage of SugoiJS which gives us the flexibility to apply decorators in run-time, either if it because of conditions or lazy-loading.
Applying decorators in run-time provides us the ability to use decorators by pure JS files as well.
Usage
Decorate - Class decorator
For applying decorator method on a call we are able to call the sugoiJS decorate method
decorateProperty(methodToApply, target)
Example
// Using ES6
import {Catch, decorate} from '@sugoi/core';
// Using nodeJS
const {Catch, decorate} = require('@sugoi/core');
​
class Validator(){
    static validate(item){
        if(!item.valid){
            throw new Error('Invalid')
        }
    }
}
decorate(Catch(()=>false),Validator);
​
Decorate - Property decorator
For applying decorator method on class property we are able to call the sugoiJS decorateProperty method
decorateProperty(methodToApply, target, property)
Example
// Using ES6
import {Catch, decorateProperty} from '@sugoi/core';
// Using nodeJS
const {Catch, decorateProperty} = require('@sugoi/core');
​
class Validator(){
    static validate(item){
        if(!item.valid){
            throw new Error('Invalid')
        }
    }
}
decorateProperty(Catch(()=>false), Validator, 'validate');
