We previously covered both the Functional and Functional Shared Instantiation methods. I showed how Functional Shared made some improvements over Functional. The next two methods I will cover are Prototypal and Pseudo-classical instantiation. They both provide improved performance over the first two methods.
If you are not familiar with prototypes, let me give you a quick summary. Every new object has a prototype chain. Prototype chains make it possible for many child objects to all reflect the properties of one parent object.
The Prototypal instantiation pattern takes advantage of prototype chains for its improvement gains over Functional and Functional Shared. Prototypal will use a prototype chain to provide access to shared methods.
The Prototypal instantiation pattern uses Object.create to generate an object with a delegation relationship. Any failed property lookups on instances will fall through to the prototype.
This reduces redundancy because new instances will have access to properties stored in the prototype.
In this post I will talk about how to create the instantiation patterns for Functional and Functional-Shared. In Part 2 of this post I talk about Prototypal and Pseudo-classical. In addition I will cover the pros and cons of each.
Today there are over half a million unfilled jobs in information technology across all sectors of the economy. These IT jobs make up ~12% of the approximately 5 million job openings making IT the largest occupational category for open jobs right now. One of the largest demands in these unfilled jobs is front-end developers.
Hack Reactor is the premier advanced immersive coding school. It was recently voted the best coding school in the world by Switchup and the best coding school in the heart of Silicon Valley by Tech Cocktail. They have a 99% job placement with graduates earning an average of $105k.
What does it take to get accepted into the “Harvard of coding schools?” Well first let me say that you have a 200% better chance of being accepted into Harvard than you do into Hack Reactor. Hack Reactor only accepts 3% of applicants. Here is a summary of my hack reactor interview process.
