inversion of control pattern for object-oriented javascript

inversion-of-control-poc.js

// the simplest possible example of inversion of control

class IOC
{
  /*
   * @type {string}
   */
  classProperty: 'hello world'
	
  constructor(/** Function */ fn) {
    // provide class context
    fn.call(this)
    return this
  }
}

// the first parameter is a function with access
// to the class context - logic can be directed 
// by the instantiating expression, rather than 
// by the class internals.
new IOC( 
  function() {
    console.log( this.classProperty )
  } 
)
