30-seconds-of-c-sharp's Issues

Enumerable.differenceWhere

Filters out all values from an enumerable for which the comparator function does not return true

Enumerable.drop

Returns a new array with n elements removed from the left.

Date.dayOfYear

use utcnow

Math.degreesToRads

Converts an angle from degrees to radians.

Date.tomorrow

Returns tomorrow's date.
You can provide a DateTimeKind value to select Local Or Utc
Default is Utc

Math.isEven

Returns true if the given number is even, false otherwise

Add CI pipeline (like in FluentTimeSpan)

Enumerable.filterNonUniqueWhere

Filters out the non-unique values in an enumerable, based on a provided comparator function (where linq statement).

Enumerable.findLast

Returns the last element for which the provided function returns a truthy value.

Change namespace to UpperCase Conplement.Snippets.*

Enumerable.countOccurences

Counts the occurrences of a value in an enumerable.

Math.factorial

Calculates the factorial of a number.

Enumerable.everyNth

Returns every nth element in an enumerable.

Date Consider using only UTC (convert to UTC if different)

Method.hz

Returns the number of times a method executed per second. hz is the unit for hertz, the unit of frequency defined as one cycle per second.

Date.minDate

Returns the minimum of the given dates.

Enumerable.difference

Returns the difference between two enumerables.

Math.isOdd

Checks if the provided integer is a prime number.

Date.isSameDate

Check if a date is the same as another date.

Date.formatDuration

Returns the human readable format of the given number of milliseconds.

Divide ms with the appropriate values to obtain the appropriate values for day, hour, minute, second and millisecond. Filter to keep only non-zero values. Create the string for each value, pluralizing appropriately. Combine the values into a string.

e.g. formatDuration(34325055574); // '397 days, 6 hours, 44 minutes, 15 seconds, 574 milliseconds'

Math.RadToDeg

Converts an angle from radians to degrees.

Math.isDivisible

Checks if the first numeric argument is divisible by the second one.

Math.fibonacci

Generates an list, containing the Fibonacci sequence, up until the nth term.

Enumerable.dropRight

Returns a new enumerable with n elements removed from the right.

Date.isAfterDate

Check if a date is after another date.

Date.getMeridiemSuffixOfInteger

Converts an integer to a suffixed string, adding am or pm based on its value.

Date.isBeforeDate

Check if a date is before another date.

Enumerable.dropRightWhile

Removes elements from the end of an array until the passed function returns true. Returns the remaining elements in the array.

Enumerable.sortedDirection

Returns Direction.Ascending if the enumerable is sorted in ascending order, Direction.Descending if it is sorted in descending order or Direction.NotSorted if it is not sorted or has only one value.

Enumerable.bifurcate

Splits values into two groups. If an element in filter is truthy, the corresponding element in the collection belongs to the first group; otherwise, it belongs to the second group.

Enumerable.differenceSelect

Returns the difference between two enumerables, after applying the provided function to each enumerable element of both.

Enumerable.countBy

Groups the elements of an enumerable based on the given function and returns the count of elements in each group as dictionary, objects as key and count of object as value (uint).

Add to conplementAG

As this is part of our Coding Dojo, I would like to have this in our companies account. I will come to you tomorrow, @DenisBiondic, to do that.

Date.maxDate

Returns the maximum of the given dates.

Enumerable.filterNonUnique

Filters out the non-unique values in an enumerable.

Enumerable.allEqual

Enumerable.chunk

Chunks an array into smaller arrays of a specified size.

Date.getDaysDiffBetweenDates

Returns the difference (in days) between two dates.

Enumerable.deepFlatten

Deep flattens an enumerable.

Maybe use recursion. Recursively flatten each element that is an enumerable.

Enumerable.hasDuplicates

Checks an enumerable for duplicate values. Returns true if duplicate values exist and false if values are all unique.

Enumerable.bubbleSort

bubbleSort uses the technique of comparing and swapping

Enumerable.compact

Removes falsey values from an array.

Filter out falsey values (false, null, 0 and "") depending on the type.

Utility.yesNo

Returns true if the string is y/yes or false if the string is n/no.

Enumerable.none

Returns true if the provided predicate function returns false for all elements in a collection, false otherwise.

Enumerable.arrayToCsv

Converts a 2D array to a comma-separated values (CSV) string.

Date.getColonTimeFromDate

Returns a string of the form HH:MM:SS from a DateTime or TimeSpan object.
