use a class in js code example

Example: javascript class example

// to create a class named 'LoremIpsum':

class LoremIpsum {
  
  // a function that will be called on each instance of the class
  // the parameters are the ones passed in the instantiation

  constructor(a, b, c) {
    this.propertyA = a;
    
    // you can define default values that way
    this.propertyB = b || "a default value";
    this.propertyC = c || "another default value";
  }
  
  // a function that can influence the object properties
  
  someMethod (d) {
    this.propertyA = this.propertyB;
    this.propertyB = d;
  }
}






// you can then call it
var loremIpsum = new LoremIpsum ("dolor", null, "sed");

// at this point:
// loremIpsum = { propertyA: 'dolor',
//                propertyB: 'a default value',
//                propertyC: 'sed' }

loremIpsum.someMethod("amit");

// at this point:
// loremIpsum = { propertyA: 'a default value',
//                propertyB: 'amit',
//                propertyC: 'sed' }
