Adobe AD0-E720 Exam - Topic 4 Question 14 Discussion
Topic #: 4
An Adobe Commerce developer was asked to customize a JavaScript component which is written as a function. How would the developer extend the native JavaScript function?
A)
B)
C)
To customize a JavaScript component that is written as a function, the developer can use option A. This option will use the prototype property of the function to extend its functionality and add new methods or properties. For example:
function Component() { // Component logic }
Component.prototype.customMethod = function() { // Custom method logic };
This will create a new method called customMethod on the prototype of the Component function, which can be accessed by any instance of the Component object. The developer can also override existing methods or properties on the prototype by reassigning them with new values.
Option B is not correct because it will not extend the native JavaScript function, but create a new function that wraps the original function. This will not allow the developer to access or modify the properties or methods of the original function. Option C is not correct because it will not extend the native JavaScript function, but create a new object that inherits from the original function. This will not allow the developer to customize the original function itself, but only its instances.
