Animation is the process in which images or objects are manipulated to appear as if they are moving. It's a powerful effect that is important for UI designers to understand and be able to use.
Forms
Forms provide a method of grouping inputs and collecting user data. As such, they are important for all front end developers.
Asynchronous Programming
Asynchronous programming is a programming method used to to run tasks asynchronously. Running tasks asynchronously can improve performance and allow applications to feel more responsive. As such, it's important for all programmers who need to write performant or responsive applications.
Hyperlink
Hyperlink, or simply a link, is a reference to data that the reader can follow by clicking or tapping. There's no web page without a hyperlink.
IFrame
The HTML Inline Frame element (iframe) represents a nested browsing context, embedding another HTML page into the current one. Web developers often use it to display content within other content.
Async-Await
The async function declaration defines an asynchronous function, which can await a response. Using the async-await pattern allows using asynchronous code while not losing readability or maintainability.
Promise
In JavaScript, a Promise is an object representing the eventual completion or failure of an asynchronous operation. It allows associating handlers with an asynchronous action's eventual success value or failure reason. It is one of the commonly used asynchronous programming techniques in JavaScript.

Event Binding
In Angular, event binding refers to binding events to methods.
One-Way Binding
In Angular, one-way binding is a type of binding where changes in the model are reflected in the HTML, but not the other way around.
Two-Way Binding
In Angular, two-way binding is a type of binding where the model and HTML are synchronized, ie, changes in the model update the HTML and changes in the HTML update the model.
Angular Pipes
In Angular, pipes are simple functions that are used to transform values in template expressions. They are useful since a pipe can be declared only once and then used throughout the whole application.
Expressions
Expressions are the bedrock of a language. They are used to translate a value or definition from one form to another.
Directives
A directive is a special token in the markup that tells the library to do something to a DOM element. It is often the simplest way to perform a required task.
Event Handling
Event-based design patterns are very common in modern applications, especially in the development of user interfaces.
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.
NPM
npm is the default package manager for Node.js. As such, it is an important tool for every Node.js developer.
Event Loop
The event loop is what allows Node.js to perform non-blocking I/O operations — despite the fact that JavaScript is single-threaded - by offloading operations to the system kernel whenever possible.
Bug Fixing
Everyone makes mistakes. A good programmer should be able to find and fix a bug in their or someone else's code.
Event Emitter
In Node.js, all objects that emit events are instances of the EventEmitter class making it one of the most commonly used classes. These objects expose an eventEmitter.on() function that allows one or more functions to be attached to named events emitted by the object.
Exceptions
Exceptions exist in most modern programming languages, making it important for a programmer to understand them and know how to handle them.
HTTP Routing
Routing describes the method of creating and directing a response for a given request (typically a URL).
CSS Advanced
Cascading Style Sheets are the styling language of the web. Knowledge about advanced CSS features is required for seasoned front-end developers.
Element Size
Setting the size of the elements on a web page is one of the basic things that any web developer or designer should know.
Arithmetic
Arithmetic is a fundamental branch of mathematics. An understanding of arithmetic concepts, and their application, is important for every candidate.
Objects
An object is a self-contained component which consists of methods and properties to make a particular type of data useful. Knowing how to create objects, and work with them, is an essential part of OOP.
Inheritance
In object-oriented programming, inheritance is the mechanism of basing a class upon another class, retaining similar implementation. Inheritance allows programmers to reuse code and is a must know topic for every programmer who works with OOP languages.
Bookmarks
A bookmark is a hyperlink that points to a location within a document, which is defined by a name that is assigned to an element. Bookmarks are used when we need to jump to a specific location within a document.
Accessibility
Accessibility refers to the design of products, devices, services, or environments for people who experience disabilities. It's important for all designers and developers to know how to optimize for people who experience disabilities.
CSS Basics
Cascading Style Sheets are the styling language of the web. Any good front-end developer requires a knowledge of basic CSS features.
Tables
A table stores data as rows and columns. From databases to HTML layouts, as a data structure they are ubiquitous. They are an important structure for developers to understand and know how to use.

Union Types
Union types allow using multiple distinct types for a function parameter or a variable.
Borders
Borders can be applied to most HTML elements within the body. This is one of the most used element decorations.
Inline Styles
Inline styles are styles that are applied directly on elements. This is one of the ways for applying styles and for some scenarios, such as for email, is the only supported way.
Selectors
Selectors are a programming pattern that can be used to select an element from a container. They are primarily used in technologies such as CSS and jQuery to apply styles to groups of elements.
CSS Layout
Cascading Style Sheets are the styling language of the web. For a front-end developer, a knowledge of CSS layouts is required.
MongoDB
MongoDB is a NoSQL document database using a JSON-like structure for documents and queries.
It's main strengths lie on the flexibility of the document schemas and easy horizontal scalability. It also allows usage of JavaScript inside queries and a file storage system.
Data Storage
To have persistence between executions of an application, reading and writing data from a form of storage must be used.
NoSQL
NoSQL databases don't mainly use tables to model data like relational databases. Instead opting to optimize for scenarios such as big data or graph traversal.
Sharding
Sharding is a technique used to separate the entries in a database across several servers in order to spread the load and achieve higher throughput.
Queries
Queries can be used to extract relevant information, based on any requirements.
Update
The update operation is used to modify existing entries in a database and is used with high frequency when dealing with mutable data.
Indexes
The proper implementation and use of indexes are important for improving the performance of database queries.
Performance Tuning
The performance of an application or system is important. The responsiveness and scalability of an application are all related to how performant an application is. Each algorithm and query can have a large positive or negative effect on the whole system.
