Is there a more concise way to simplify this code snippet?
var controller = function(){
/*--- constructor ---*/
};
controller.prototype.function1 = function(){
//Prototype method1
}
controller.prototype.function2 = function(){
//Prototype method2
}
controller.prototype.function3 = function(){
//Prototype method3
}
return controller
I'm currently using require.js and I'm looking for a way to streamline the controller.prototype declarations.
If you find yourself needing to repeat this process in multiple places, it may be beneficial to create a helper function to streamline the task:
function extendPrototype(constructor, methods){
for(var key in methods) {
if(methods.hasOwnProperty(key)) {
constructor.prototype[key] = methods[key];
}
}
}
var controller = function(){
//constructor
};
extendPrototype(controller, {
method1 : function(){
//Prototype method1
},
method2: function(){
//Prototype method2
},
method3 : function(){
//Prototype method3
}
});
return controller;
It's worth mentioning jQuery's extend method as it offers more functionality compared to the custom helper function mentioned earlier:
var controller = function(){ /* ctor */};
return $.extend(controller.prototype,{
method1 : function(){
//Prototype method1
},
method2: function(){
//Prototype method2
},
method3 : function(){
//Prototype method3
}
});
Other libraries like underscore's extend method or Lo-Dash's assign method offer similar functionalities.
Utilizing ES6 features allows for the use of object destructuring as well.
function Bar() {
}
Bar.prototype = {
...Bar.prototype,
methodOne() {},
methodTwo() {},
methodThree() {}
}
Add the function1 method to the controller prototype using Object.assign()
