TypeScript
The TypeScript programming language is a strict superset of JavaScript. It adds optional static typing and class-based object-oriented programming to the language
Arrays
An array is a container of a fixed number of objects of a similar type. It is a fundamental component of most programming languages.
OOP
Object-oriented programming is a paradigm based on encapsulating logic and data into objects, which may then contain fields and procedures. Many of the most widely used programming languages are based on OOP, making it a very important concept in modern programming.
Public
Public questions (free account) are common interview questions. They are great for practicing, or if you want to filter candidates using the classic problems.
The following code initializes three types representing the colors: red, green and blue.
type ColorType = [string, number, number, number];
let red: ColorType = ['Red', 1, 0, 0];
let green: [string, number, number, number] = ['Green', 0, 1, 0];
let blue = ['Blue', 0, 0, 1];

Types
Many programming languages implement a type system. A type system is a set of constraints that a given variable must obey in order to be considered a predefined type. The main purpose of a type system is to reduce the likelihood of bugs in a computer program. All good developers should be able to work with types.

AngularAngular
Angular is a widely used, complete, JavaScript-based open-source, front-end web application framework. As it is the front end of the MEAN stack it's important for front end engineers to have experience with or knowledge of Angular.
Structural directive
A structural directive changes the model it is a part of by adding and removing components. A crucial tool for programmers building applications using frameworks.
Components
Components are used in many frameworks and languages as the building blocks of an application.
Expressions
Expressions are the bedrock of a language. They are used to translate a value or definition from one form to another.

Spread
Spread syntax allows an iterable to be expanded in places where zero or more arguments or elements are expected. As a core language feature of many programming languages, it's important for all developers to be familiar with.
Services
A service is a function, or object, that is available for, and provides data or functionality to an application. It's important to understand a services responsibility, and to encapsulate logic and features when possible.
Data binding
Data binding is a technique for synchronizing data between a component and DOM. For this reason, it’s important for all web developers.
