Package Exports

object-js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (object-js) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

npm install --save object-js

Usage

import js, { Obj } from 'object-js';

class Thing extends Obj {

  constructor(prop) {
    this.prop = prop;
  }
  
  equals(value) {
    return js.doesExtend(value, Thing) && value.prop === this.prop; 
  }

  hashCode() {
    if (!this._hashCode) {
      this._hashCode = js.hash(this.prop);
    }
    return this._hashCode;
  }
}


const thing1 = new Thing('abc');
const thing2 = new Thing('abc');
const thing3 = new Thing('bcd');

js.equals(thing1, thing2)   // true
js.equals(thing2, thing3)   // false
