Inheritance

Classical Inheritance

A class is like a blueprint, a description of objects to be created. Classes inherit from classes and create subclass relationships. Instantiation happens via new operator. The class keyword in Javascript is just a function

Class Foo{}
typeof Foo // 'function'

/** Creates a new store, which is a tiny evented state container.
 *  @example
 *    let store = createStore();
 *    store.subscribe( state => console.log(state) );
 *    store.setState({ a: 'b' });   // logs { a: 'b' }
 *    store.setState({ c: 'd' });   // logs { c: 'd' }

First Time

• Cache Everything -- NGINX, CDN
• Use CDN ( and multiple cdn's because generally broswer restricts concurrent connections)
• Move scripts to body (i.e below the fold)
• Minimize head tag because this is blocking
• HTTP/2 - Stream and Push
• Stream HTML and CSS
• Use appropriate images
• Server Side Rendering of First Page
• Analyze Critical Rendering Path

Tech Stack

Type of Programming

Prefer functional, reactive and declarative programming instead of imperative programming.

Prefer Test Driven Development to ensure deterministic code base

Functional Programming

Ramda is a trusted library to write functional code. This will ensure composibility of functions and testability. Ramda gives you a lot of constructs to ensure that code is concise
