What is anti pattern in C#?
In fact the same bad code tends to crop up over and over, which is why we call them “Anti-Patterns”. Anti-patterns are common responses to a recurring problem that are ineffective and highly counterproductive. In a series of short lectures I am going to show you the most common C# anti-patterns.
What is helper code?
A Helper class is a lesser known code smell where a coder has identified some miscellaneous, commonly used operations and attempted to make them reusable by lumping them together in an unnatural grouping.
What is a helper function in programming?
A helper function is a function that performs part of the computation of another function. Helper functions are used to make your programs easier to read by giving descriptive names to computations. They also let you reuse computations, just as with functions in general.
What are some examples of AntiPatterns?
The term was popularized three years later by the book AntiPatterns, which extended its use beyond the field of software design to refer informally to any commonly reinvented but bad solution to a problem. Examples include analysis paralysis, cargo cult programming, death march, groupthink and vendor lock-in.
What is a bad pattern?
A pattern is an idea of how to solve a problem of some class. An anti-pattern is an idea of how not to solve it because implementing that idea would result in bad design. An example: a “pattern” would be to use a function for code reuse, an “anti-pattern” would be to use copy-paste for the same.
What is a helper service?
Service able to serve some clients, and often this is a SOA specific entity. Helper provides a set of methods which commonly are pure functions. Often if you can make method a static method – this is a helper method, it does not depends on any class state and does not affect it as well.
What is helper column in Excel?
A helper column is a non-technical term to describe a column added to a set of data to help simplify a complex formula or an operation that would be otherwise difficult. In the example above, a helper column is used to concatenate first and last names, so that VLOOKUP can be used to find department using both names.
Should functions be small?
A function should be as short as possible. A function may grow if it needs to enforce sequential coupling rules, e.g. if there are several steps that need to happen in a particular order. On the other hand, the individual steps could be farmed out to separate functions if the function gets too big.
