Documentation
The following functions are currently implemented:
assertArraysEqual(arr1, arr2)
: Takes in two arrays as arguments, checks if they are equal and logs an appropriate message to the console
assertObjectsEqual(obj1, obj2)
: Takes in two objects as arguments, checks if they are equal and logs an appropriate message to the console
assertEqual(val1, val2)
: Uses strict comparison of two values
countLetters(sentence)
: Take in a sentence as a string and returns a count of each of the letters in that string
countOnly(allItems, itemsToCount)
: Takes in a collection of allItems and return counts for a specific subset of those itemsToCount
eqArrays(arr1, arr2)
: Takes in two arrays as arguments and evaluates if they are a perfect match
eqObjects(object1, object2)
: Takes in two objects as arguments and evaluates if they are a perfect match
findKey(obj, callback)
: Takes in an object and a call back function and returns the first key that satisfies the callbacks condition. If no key matches the given value it will return undefined
findKeyByValue(obj, val)
: Takes in an object and a specific value and returns the first key which matches that value. If no key matches the given value it will return undefined
flatten(arr)
: Flattens a nested array elements into a single array
head(arr)
: Returns the first element of an array
letterPositions(sentence)
: Will return all the indices (zero-based positions) in the sentence string where each character is found
map(arr, callback)
: Takes in an array and a callback function and returns a new array based on the conditions of the callback
middle(arr)
: Returns the middle value of an array. If array is even, returns the two elements in the middle.
tail(arr)
: Returns an array with the first element removed
takeUntil(data, callback)
: The function will slice an array from the beginning until the condition of the given callback function is satisfied
