Documentation
The following functions are currently implemented:
Assert Functions:
assertEqual(actual, expected)
: Compares two values (numbers, strings, or Booleans) and asserts a message telling us if they are equal or not.assertArraysEqual(array1, array2)
: Compares two arrays and asserts a message telling us if they are equal or not.assertObjectsEqual(object1, object2)
: Compares two objects and asserts a message telling us if they are equal or not.
Counting Functions:
countLetters(string)
: Counts the letters in a given string.countOnly(allItems, itemsToCount)
: Takes in an array of strings and an object of truthy values denoting the specific subset to count, and returns counts for the subset.
Equality Functions
eqArrays(array1, array2)
: Takes in two arrays, returns true if they are equal and false if they are not.eqObjects(object1, object2)
: Takes in two objects, returns true if they are equal and false if they are not.
Search Functions
findByKeyValue(object, value
: Takes in an object and a value, scans the object and returns the first key which contains the given value.findKey(object, callback)
: Takes in an object and a callback, scans the object and returns the first key for which the callback returns a truthy value. Returns undefined if no key is found.
String Function
letterPositions(sentence)
: Takes in a string and returns an object of the string's letters and their indexed poitions.
Array Functions
head(array)
: Returns the first element of an array.tail(array)
: Removes the first element from an array and returns the resulting "tail".middle(array)
: Returns the middle element (or middle two elements) of an array.map(array, callback)
: Takes in an array to map and a callback function. Returns a new array based on the resuls of the callback function.takeUntil(array, callback)
: Takes in an array and a callback function and cuts the array when the callback function returns 'false'.without(source, itemsToRemove)
: Takes in an array and an array item(s) to remove. Removes these items from the array.
