Constructor Pattern
Change MyLibrary to whatever namespace you’d like to use for your library. Constructors start with a capital letter.
Examples
// Create new instances of the constructor
let dugg = new MyLibrary();
let kevin = new MyLibrary(4);
// Run methods
dugg.add(2);
kevin.subtract(1);
let total = dugg.total;
The Boilerplate
/**
* Constructor Pattern Boilerplate
*/
let MyLibrary = (function () {
/**
* Create the Constructor object
* @param {Number} start The starting amount
*/
function Constructor (start = 0) {
this.total = start;
}
/**
* Add money to the total
*/
Constructor.prototype.add = function (num = 1) {
this.total = this.total + num;
};
/**
* Remove money from the total
*/
Constructor.prototype.subtract = function (num = 1) {
this.total = this.total - num;
};
return Constructor;
})();
