Styling
Styling user interfaces according to the specification is a daily routine for a front-end developer.
Multithreading
Multi-threading allows a process to make more efficient use of modern hardware by allowing code to execute asynchronously. It can drastically improve the performance of any app; however, it can be tricky to get right, making this an important topic for any programmer.
Joins
A normalized database is normally made up of multiple tables. Joins are, therefore, required to query across multiple tables.
Union
In mathematics, a union typically involves testing if an element exists in two or more sets. This definition also applies as an operator and function in various programming languages. As one of the most common collection operations, alongside intersection, it's an important topic for any candidate to understand.
DOM manipulation
Dynamically accessing and updating user interface elements is an important part of most modern web applications.
Event handling
Event-based design patterns are very common in modern applications, especially in the development of user interfaces.
Data structures
Choosing the right data structure to solve a problem can have huge implications on the performance of an application. Knowing when to use a specific data structure is one of the most important skills for a programmer.
Iteration
Iteration is the act of repeating a process, or cycling through a collection. Iteration is one of the fundamental flow control tools available to developers.
ASP.NET (Core) MVC
ASP.NET (Core) MVC extends the traditional ASP.NET framework and allows developers to author pages using the model–view–controller (MVC) architecture.
MVC pattern
The MVC pattern is designed to split an application into three logical parts: the model, the view and the controller. The model is responsible for the data and the rules of the application. The view is responsible for outputting that information, and the controller is responsible for accepting input from a user and forwarding it to the model or the view. Every web developer should be familiar with the MVC pattern and the benefits of encapsulating these components.
URL routing
URL routing is an application's interface to the web.
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.
Constraints
Constraints are used to define rules and relationships. They are applied to a dataset. A constraint may take many forms, such as x ≤ 5 in a programming language and a NOT NULL constraint in a SQL table definition.
Database schema
A database schema defines how data is stored in a database. An SQL database uses a schema to define tables consisting of rows and columns that use fixed data types to store data. Formalizing how data is stored is the first step towards building an application or service.
Delete
The delete statement is used to delete records in a table and is one of the four basic CRUD functions (create, read, update, and delete) required for working with any persistent storage.
Refactoring
The process of restructuring existing computer code without changing its external behavior. It is essential for keeping code readable and maintainable.
Sorting
Every programmer should be familiar with data-sorting methods, as sorting is very common in data-analysis processes.
Update
The UPDATE statement is used to modify the existing records in a table and is one of the most used operations for working with the database.
Views
A database view is a result set that is defined by a stored query, the results of which can can also be queried. As a fundamental and widely used database construct, it's useful for candidates to understand how and when they should be used.
Animation
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.
Actions
In ASP.NET MVC, an action is a controller method which is called in response to a client request. Actions are one of the basic components of ASP.NET MVC.
Random
Random number generators are used to generate random numbers and/or symbols. There are a wide variety of random number generators each with very specific use cases, as such it's important for all developers to know and understand when to use each type.
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.
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.
Algorithmic thinking
When designing and/or analyzing an algorithm or data structure, it is important to consider the performance and structure of an implementation. Algorithmic thinking is one of the key traits of a good programmer, especially one working on complex or performance-critical code.
Graphs
Many real-life situations are best modeled by graphs. Therefore, an in-depth knowledge of graph data structures is important for a good programmer.
Monkey patching
Monkey Patching is a method of either adding new or overriding existing functionality without the creation of a new type. As such it's an important tool for developers to be familiar with.
Extension methods
Extension methods enable are method of extending existing types without extending the type, recompiling or modifying the original type. They are a useful feature of developers who want to write and maintain clean and concise code.
Dynamic programming
Dynamic programming methods for code optimization can be very useful to a programmer who understands them.
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.
Razor
Razor is an ASP.NET programming syntax used to create dynamic web pages with the C# or Visual Basic .NET programming languages. It is the most popular of the view engine syntaxes available in ASP.NET MVC.
Data Annotations
Data Annotations are a set of predefined .NET classes that allow easy data validation. As such, they are important for developers who want to avoid writing boilerplate validation code.
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.
TDD
Test-driven development (TDD) is a software development process that relies on the repetition of a very short development cycle: requirements are turned into very specific test cases, based on which the software is improved only in order to pass the new tests. TDD is an essential skill for modern programmers.
Classes
A class is one of the most widely used and primary structures used in object-oriented programming. As such it's important for any developer to have a working knowledge of how to use it.
ECMAScript 2015
ECMAScript 2015 adds a significant number of features to JavaScript, including classes, modules and range based loops. As such it's important for any JavaScript developer to understand.
Test case design
Being able to create a set of test cases that ensure adequate test coverage is a key skill for creating a successful test. It is desirable for the test suite also to be optimal, i.e. to minimize test execution effort and time without affecting the test coverage.
Recursion
A good programmer should be familiar with when to use recursive functions, since they can provide elegant solutions for complex problems.
